He led an awesome life. Period.
Being him (or with him) was never boring, I'm sure. My teacher told me that sometimes geniuses are weirdos. I think Feynman was one of them.
One of my favorite parts was when the dean Eisenhart asked his students if some of them would like to volunteer to be hypnotized. And Feynman screamed out loud, "MEEEEEEEEEEEE!" And he was the only one. The dean only said, "Yes, of course, I knew you would volunteer, Mr. Feynman, but I was wondering if there would be anybody else."
Another was when one day he realized that physics disgusted him a little bit, while he used to enjoy it before. He enjoyed it because he used to play with it. He didn't do it for the development of knowledge or whatever. He did it because he liked it, because it amused him. So he figured out the motion of a rotating plate for the fun of it, not because it was important.
That taught me something. Geodesy does bore me sometimes. I've lost the excitement I felt when I first learned it. Perhaps I should do what Feynman did: playing with Geodesy.
What I like about him most is his persistence. He would never give up until he solved whatever he was trying to solve--puzzles, physics problems, broken radio. He was also very curious. He learned how to play samba music and to paint. It made me realize that age doesn't, and shouldn't, stop you from learning. Sometimes, you think that you're too old to learn something--play the violin, learn a new language. Feynman proved it wrong, that you could be good--if not excellent--even if you didn't start at a very young age.
Lessons learned: Integrity; don't be afraid of trying new things; have fun with whatever you do.
"So I have just one wish for you the good luck to be somewhere where you are free to maintain the kind of integrity I have described, and where you do not feel forced by a need to maintain your position in the organization or financial support, or so on, to lose your integrity. May you have that freedom." (last paragraph)
