When I got to 40 or so... I had the sense when I looked back over my life I would actually see a mess of decisions, a few of which I had thought about, some of which I had sort of stumbled on, and many that I had no control over whatsoever.
At the end of the day it's not about what you have or even what you've accomplished... it's about who you've lifted up, who you've made better. It's about what you've given back.
