It's not easy to retire at 31. In one respect I was glad I was done. But after a few years of having fun I got a little restless. When you're 33 34 and you don't have a focus you can get kind of lost. As a man you feel a little bit unfulfilled.

Sometimes a technology is so awe-inspiring that the imagination runs away with it - often far far away from reality. Robots are like that. A lot of big and ultimately unfulfilled promises were made in robotics early on based on preliminary successes.

Consult not your fears but your hopes and your dreams. Think not about your frustrations but about your unfulfilled potential. Concern yourself not with what you tried and failed in but with what it is still possible for you to do.

I remember opening my dad's closet and there were like 40 suits every color of the rainbow plaid and winter and summer. He had two jewelry boxes full of watches and lighters and cuff links. And just... he was that guy. He was probably unfulfilled in his life in many ways.
