我为我们没有做的许多事情感到骄傲，就像为我们做过的事情感到骄傲一样。创新就是对一千件事情说不。
I will hazard a prediction. When you are 80 years old， and in a quiet moment of reflection narrating for only yourself the most personal version of your life story， the telling that will be most compact and meaningful will be the series of choices you have made. In the end， we are our choices. Build yourself a great story.
Your time is limited, don't waste it living someone else's life.
