Jeff Bezos, founder of Amazon, gave a commencement address at Princeton that I found moving.  Perhaps you will too.  The talk was entitled “We are what we choose” and one of the points he makes is that it is easier to be clever than kind. He concluded his remarks with:

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.
