Are you playing to make money or playing to win? The reason you do the things you do is even more important than the things you are doing.
If you are playing to make money, you become obsessed with ‘milking the cow’, squeezing out all the money you can. If you play to win on the other hand, you obsessively build better products, make better choices and drive forward. And as history shows us over and over again: it is the best products that bring in the most profits in the long run.
In retrospect, playing to win is what has made Facebook such a massive hit today. Yahoo! on the other hand is nowadays playing to make money, there is no fire or drive to win anything in that company again.
