Analogy for Invention vs Innovation

If invention is a pebble tossed in the pond, innovation is the rippling effect that pebble causes. Someone has to toss the pebble. That’s the inventor. Someone has to recognize the ripple will eventually become a wave. That’s the entrepreneur.
Entrepreneurs don’t stop at the water’s edge. They watch the ripples and spot the next big wavebefore it happens. And it’s the act of anticipating and riding that “next big wave” that drives the innovative nature in every entrepreneur.

Repair a puncture bicycle tire

On Monday night, surprisingly discovered the tire was flat, after little inspection, found the culprit to be a thorn from some plant. 


The Culprit!!

The patch from repair bought from Daiso.
LBS bike quoted me $9 for changing a new tube, 
but I think it is not necessary as there is no need to 
create an unnecessary rubbish and I get to save $7.
As bonus, I've learnt how to patch a puncture tire cheaply.

 And Voila!!! Back to roll again!

Bough a Tern - Link C7






This is the part I like the most. 


Bought a Tern Link C7 foldable bike today, good price and hopefully can rides for long time. Based on 2 minutes rides experience, the frame feel solid and easy to control.
However, this is more like a city bike and not suitable for off road. By the way, I don't do off road.

The Paradox of Our Time


The Paradox of Our Time in History
The paradox of our time in history is that we have taller buildings, but shorter tempers; wider freeways, but narrower viewpoints; we spend more, but have less; we buy more, but enjoy it less.

We have bigger houses and smaller families; more conveniences, but less time; we have more degrees, but less sense; more knowledge, but less judgment; more experts, but more problems; more medicine, but less wellness.

We drink too much, smoke too much, spend too recklessly, laugh too little, drive too fast, get angry too quickly, stay up too late, get up too tired, read too seldom, watch TV too much, and pray too seldom.

We have multiplied our possessions, but reduced our values. We talk too much, love too seldom, and hate too often. We've learned how to make a living, but not a life; we've added years to life, not life to years.

We've been all the way to the moon and back, but have trouble crossing the street to meet the new neighbor. We've conquered outer space, but not inner space; we've done larger things, but not better things.

We've cleaned up the air, but polluted the soul; we've split the atom, but not our prejudice.

We write more, but learn less; we plan more, but accomplish less. We've learned to rush, but not to wait; we have higher incomes, but lower morals; we have more food, but less appeasement; we build more computers to hold more information to produce more copies than ever, but have less communication; we've become long on quantity, but short on quality.

These are the times of fast foods and slow digestion; tall men, and short character; steep profits, and shallow relationships. These are the times of world peace, but domestic warfare; more leisure, but less fun; more kinds of food, but less nutrition.

These are days of two incomes, but more divorce; of fancier houses, but broken homes. These are days of quick trips, disposable diapers, throw away morality, one-night stands, overweight bodies, and pills that do everything from cheer to quiet to kill. 

It is a time when there is much in the show window and nothing in the stockroom; a time when technology has brought this letter to you, and a time when you can choose either to make a difference, or to just hit delete...

Excel Formula List

1、查找重复内容公式:=IF(COUNTIF(A:A,A2)>1,"重复","")。
2、用出生年月来计算年龄公式:=TRUNC((DAYS360(H6,"2009/8/30",FALSE))/360,0)。
3、从输入的18位身份证号的出生年月计算公式:=CONCATENATE(MID(E2,7,4),"/",MID(E2,11,2),"/",MID(E2,13,2))。
4、从输入的身份证号码内让系统自动提取性别,可以输入以下公式:
=IF(LEN(C2)=15,IF(MOD(MID(C2,15,1),2)=1,"男","女"),IF(MOD(MID(C2,17,1),2)=1,"男","女"))公式内的“C2”代表的是输入身份证号码的单元格。
 1、求和: =SUM(K2:K56)  ——对K2到K56这一区域进行求和;
2、平均数: =AVERAGE(K2:K56)  ——对K2 K56这一区域求平均数;
3、排名: =RANK(K2,K$2:K$56)  ——对55名学生的成绩进行排名;
4、等级: =IF(K2>=85,"优",IF(K2>=74,"良",IF(K2>=60,"及格","不及格")))
5、学期总评: =K2*0.3+M2*0.3+N2*0.4 ——假设K列、M列和N列分别存放着学生的“平时总评”、“期中”、“期末”三项成绩;
6、最高分: =MAX(K2:K56) ——求K2到K56区域(55名学生)的最高分;
7、最低分: =MIN(K2:K56) ——求K2到K56区域(55名学生)的最低分;
8、分数段人数统计:
(1) =COUNTIF(K2:K56,"100") ——求K2到K56区域100分的人数;假设把结果存放于K57单元格;
(2)  =COUNTIF(K2:K56,">=95")-K57 ——求K2到K56区域95~99.5分的人数;假设把结果存放于K58单元格;
(3)=COUNTIF(K2:K56,">=90")-SUM(K57:K58)  ——求K2到K56区域90~94.5分的人数;假设把结果存放于K59单元格;
(4)=COUNTIF(K2:K56,">=85")-SUM(K57:K59)  ——求K2到K56区域85~89.5分的人数;假设把结果存放于K60单元格;
(5)=COUNTIF(K2:K56,">=70")-SUM(K57:K60)  ——求K2到K56区域70~84.5分的人数;假设把结果存放于K61单元格;
(6)=COUNTIF(K2:K56,">=60")-SUM(K57:K61)  ——求K2到K56区域60~69.5分的人数;假设把结果存放于K62单元格;
(7) =COUNTIF(K2:K56,"<60 p="">说明:COUNTIF函数也可计算某一区域男、女生人数。
如:=COUNTIF(C2:C351,"男") ——求C2到C351区域(共350人)男性人数;
9、优秀率: =SUM(K57:K60)/55*100
10、及格率: =SUM(K57:K62)/55*100
11、标准差: =STDEV(K2:K56) ——求K2到K56区域(55人)的成绩波动情况(数值越小,说明该班学生间的成绩差异较小,反之,说明该班存在两极分化);
12、条件求和: =SUMIF(B2:B56,"男",K2:K56) ——假设B列存放学生的性别,K列存放学生的分数,则此函数返回的结果表示求该班男生的成绩之和;
13、多条件求和: {=SUM(IF(C3:C322="男",IF(G3:G322=1,1,0)))} ——假设C列(C3:C322区域)存放学生的性别,G列(G3:G322区域)存放学生所在班级代码(1、2、3、4、5),则此函数返回的结果表示求一班的男生人数;这是一个数组函数,输完后要按Ctrl+Shift+Enter组合键(产生“{……}”)。“{}”不能手工输入,只能用组合键产生。
14、根据出生日期自动计算周岁:=TRUNC((DAYS360(D3,NOW( )))/360,0)
———假设D列存放学生的出生日期,E列输入该函数后则产生该生的周岁。
15、在Word中三个小窍门:
①连续输入三个“~”可得一条波浪线。
②连续输入三个“-”可得一条直线。
连续输入三个“=”可得一条双直线。
一、excel中当某一单元格符合特定条件,如何在另一单元格显示特定的颜色比如:
A1〉1时,C1显示红色
0A1<0 p="">方法如下:
1、单元击C1单元格,点“格式”>“条件格式”,条件1设为:
公式 =A1=1
2、点“格式”->“字体”->“颜色”,点击红色后点“确定”。
条件2设为:
公式 =AND(A1>0,A1<1 p="">3、点“格式”->“字体”->“颜色”,点击绿色后点“确定”。
条件3设为:
公式 =A1<0 p="">点“格式”->“字体”->“颜色”,点击黄色后点“确定”。
4、三个条件设定好后,点“确定”即出。
二、EXCEL中如何控制每列数据的长度并避免重复录入
1、用数据有效性定义数据长度。
用鼠标选定你要输入的数据范围,点"数据"->"有效性"->"设置","有效性条件"设成"允许""文本长度""等于""5"(具体条件可根据你的需要改变)。
还可以定义一些提示信息、出错警告信息和是否打开中文输入法等,定义好后点"确定"。
        2、用条件格式避免重复。
选定A列,点"格式"->"条件格式",将条件设成“公式=COUNTIF($A:$A,$A1)>1”,点"格式"->"字体"->"颜色",选定红色后点两次"确定"。
这样设定好后你输入数据如果长度不对会有提示,如果数据重复字体将会变成红色。
三、在EXCEL中如何把B列与A列不同之处标识出来?
(一)、如果是要求A、B两列的同一行数据相比较:
假定第一行为表头,单击A2单元格,点“格式”->“条件格式”,将条件设为:
“单元格数值” “不等于”=B2
点“格式”->“字体”->“颜色”,选中红色,点两次“确定”。
用格式刷将A2单元格的条件格式向下复制。
B列可参照此方法设置。
(二)、如果是A列与B列整体比较(即相同数据不在同一行):
假定第一行为表头,单击A2单元格,点“格式”->“条件格式”,将条件设为:
“公式”=COUNTIF($B:$B,$A2)=0
点“格式”->“字体”->“颜色”,选中红色,点两次“确定”。
用格式刷将A2单元格的条件格式向下复制。
B列可参照此方法设置。
按以上方法设置后,AB列均有的数据不着色,A列有B列无或者B列有A列无的数据标记为红色字体。
四、EXCEL中怎样批量地处理按行排序
假定有大量的数据(数值),需要将每一行按从大到小排序,如何操作?
由于按行排序与按列排序都是只能有一个主关键字,主关键字相同时才能按次关键字排序。所以,这一问题不能用排序来解决。解决方法如下:
1、假定你的数据在A至E列,请在F1单元格输入公式:
=LARGE($A1:$E1,COLUMN(A1))
用填充柄将公式向右向下复制到相应范围。
你原有数据将按行从大到小排序出现在F至J列。如有需要可用“选择性粘贴/数值”复制到其他地方。
注:第1步的公式可根据你的实际情况(数据范围)作相应的修改。如果要从小到大排序,公式改为:=SMALL($A1:$E1,COLUMN(A1))
五、巧用函数组合进行多条件的计数统计
例:第一行为表头,A列是“姓名”,B列是“班级”,C列是“语文成绩”,D列是“录取结果”,现在要统计“班级”为“二”,“语文成绩”大于等于104,“录取结果”为“重本”的人数。统计结果存放在本工作表的其他列。
公式如下:
=SUM(IF((B2:B9999="二")*(C2:C9999>=104)*(D2:D9999="重本"),1,0))
输入完公式后按Ctrl+Shift+Enter键,让它自动加上数组公式符号"{}"。
六、如何判断单元格里是否包含指定文本?
假定对A1单元格进行判断有无"指定文本",以下任一公式均可:
=IF(COUNTIF(A1,"*"&"指定文本"&"*")=1,"有","无")
=IF(ISERROR(FIND("指定文本",A1,1)),"无","有")
求某一区域内不重复的数据个数
例如求A1:A100范围内不重复数据的个数,某个数重复多次出现只算一个。有两种计算方法:
一是利用数组公式:
=SUM(1/COUNTIF(A1:A100,A1:A100))
输入完公式后按Ctrl+Shift+Enter键,让它自动加上数组公式符号"{}"。
二是利用乘积求和函数:
=SUMPRODUCT(1/COUNTIF(A1:A100,A1:A100))
七、一个工作薄中有许多工作表如何快速整理出一个目录工作表
1、用宏3.0取出各工作表的名称,方法:
Ctrl+F3出现自定义名称对话框,取名为X,在“引用位置”框中输入:
=MID(GET.WORKBOOK(1),FIND("]",GET.WORKBOOK(1))+1,100)
确定
2、用HYPERLINK函数批量插入连接,方法:
在目录工作表(一般为第一个sheet)的A2单元格输入公式:
=HYPERLINK("#'"&INDEX(X,ROW())&"'!A1",INDEX(X,ROW()))
将公式向下填充,直到出错为止,目录就生成了。

Alex Ferguson's Lessons

Sir Alex Ferguson was recently invited to help teach a class at Harvard Business School as a follow up to one professor's in-depth case study on him. In the class, Ferguson imparted his vast wisdom on the students in a manner similar to Jose Mourinho's class for 200 American coaches at UCLA last summer. These are lessons Ferguson shared...
"Lesson 1: On your very first day at a new job, fight a python with your bare hands in front of your superiors and underlings. This is very important and it accomplishes two things. First, it makes your superiors too afraid to ever try and sack you because they know you have access to pythons. Second, it makes your underlings too afraid to go against your wishes because they know that if you'll fight a python, you'll fight them.
"Lesson 2: Let your enemies believe myths about you and your influence. Like how officials grant you more time or penalize your competitors when it can help you. Or how certain officials are essentially your employees. They'll end up intimidating themselves with these tales and make themselves look stupid. It will also distract them from the grander and far less obvious conspiracies involving magnets and hemorrhoids you perpetrate without them knowing.
"Lesson 3: It's important to show the people you depend on that you care for them very deeply. But it's even more important to let them know when they've let you down. People call my method of doing this "the hairdryer treatment," but yelling at them until their face starts to melt is only the beginning. The part that leaves a lasting impact is when I mysteriously appear while they're making love and stare directly into their eyes while loudly chewing gum when it's too late for them to stop what they're doing. This creates a bond of shame and subordination that cannot be broken.
"Lesson 4: Never buy anything from Portugal for £7 million without seeing it first. I don't care how much red wine you've had when your former assistant calls to tell you about it. Do not buy it. You can loan it to a Turkish company and hope they lose it or forget to give it back, but they won't. They won't...
"Lesson 5: People say a lot of cruel things about gingers, but they're actually made entirely of magic and bad tackles. Keep one around for as long as you can.
"Lesson 6: The press is a bunch of scabby tossbags. Never speak to them if you can help it. If you must speak to them, treat them with obvious contempt and think about how they are disappointments to everyone they care about the whole time. They will actually think you enjoy their company.
"Lesson 7: Kick a boot at David Beckham's head. That's not a metaphor of any kind, I mean that literally. Kick a boot at David Beckham's head. You'll never feel more alive and his dumb handsome face will never see it coming.
"Lesson 8: When you're in the twilight of your career and you know your time on this planet is starting to wind down, try and share everything you've learned with the next generation. Be open and honest with them. And then, after you've told them all your secrets and they leave that room -- hopefully with a new and more informed perspective on things -- you can fly back to Manchester and cackle the whole way because those Harvard idiots actually believed they were so special that you'd tell them the good stuff that you won't even tell your own son. Anyway, you don't get a statue of yourself built outside your office while you're still working there just for doing what someone else told you to do."

The "Mourinho Way"

"There is not just one or two reasons [for his success]. There are a lot of factors and they must work in unison," he told his students. From RealMadrid.com:
From this point José Mourinho then covered essential topics such charismatic leadership, dividing and spreading the workload, intellectual stimulation, etc., all aspects that are "crucial for the evolution and success of the group". With regard to teamwork, the coach explored the topic in depth for some time, but not without making a joke or two along the way: "I'm not even the boss at home, that's my wife. How am I supposed to run my club? When everyone grows in the same direction and I can see they are doing so, I'm very happy and everything is much easier".
Those of you who could not attend this seminar are in luck, though. Since we have transcribed the key points Mourinho shared. Here's what he said...
"For all of you, trying to be special will not be easy. But for me it is very easy. I will tell you exactly how I do it because I know that even with these steps, none of you will be able to compare to me.
"Step 1: Take Ricardo Carvalho wherever you go. Moving to a new club? Take Ricardo Carvalho. Going to see a movie? Take Ricardo Carvalho. Appointment with the podiatrist? Take Ricardo Carvalho. Going to Inter? Don't take Ricardo Carvalho. This is the exception that makes the rule. Also, he hates veal milanese like Arsene Wenger hates spending money.
"Step 2: Engage in so many mind games that your toughest opponent decides to leave football entirely even though he is younger than you and has been extremely successful in a short amount of time with the club he loves more than all others. Good night, Pepper-plant.
"Step 3: Let Rafa Benitez swim in your wake. When Rafa takes over a club after you, what you did will suddenly look even better than it already was. This is the magic of Rafa. And he has more conspiracy theories than Mel Gibson character in the movie Conspiracy Theory.
"Step 4: Don't be afraid to poke people in the eye. Who knows. One day they could be manager of Barcelona. Best to instill a fear of your poke now."
"Step 5: Tell Pepe that each of your opponents killed one of his pets when he was a child and that he must get his revenge. Step 5A: Laugh when he does it. Hahahahahahaha.
"Step 6: Are you Jose Mourinho? Of course not. Only I am Jose Mourinho and therefore only I am the Special One. So all of you should stop wasting your time and do something else. Go next door and take a cooking class. Make me something delicious to eat. But for the love of all that is good, do not make veal milanese because Ricardo Carvalho will freak out on you."
