A good anecdote re: the value in (not being afraid of) striking up conversations with strangers. I think a lot of people, myself included, have a tendency to shy away from such encounters - ask the right questions, and you can get really interesting stories.
On the other hand, the man's comment about "wanting to be his own man" got me thinking about doing startups for the sake of not working at a large company. While it's probably a nice touch, I think I'm getting more cautious about letting that be a determining factor.
