alt Hacker NewsI defined success for myself quite a few years ago: I want to leave the world better than I found it. No high aspirations, no figure. Just better than it was.
Some of that is political advocacy. Some of that is open source code that should exist. Some of that is helping a neighbor. I don't need to hit a certain bar, I just need to know that in a given interaction or situation, I am trying to make things... at least a little better.
That also scales well to differing life decisions. The video game I'm playing, can I get people to play a little nicer with each other and have more fun? Workplaces are full of dumb stuff, success is making it at least a little better. Turns out I have kids now. Wasn't the plan, but now my obligation is to make sure my involvement in their lives is positive. Not a specific bar I have to achieve, but you know, someday I hope someone appreciates how I chose to live my life.
"To laugh often and much, to win the respect of intelligent people and the affection of children, to earn the appreciation of honest critics and endure the betrayal of false friends, to appreciate beauty, to find the best in others, to leave the world a bit better, whether by a healthy child, a garden patch... to know even one life has breathed easier because you have lived. This is to have succeeded!" - Emerson
