That's a fair point. All I'm getting at though, is that there's a lot to be said for taking a swing or two when you're younger and have more time for "second chances" if you fail. At my age, if I fail, I don't see starting all over again as being in the cards.
I think one of the biggest things people should learn from their first startup dying is that it's better to say here ran a coward than here died a lion though.
