The funny thing is that memory is a tricky bastard, and you're likely to remember yourself with no pride on something you did that went wrong, when at the time you were actually doing it you were very much committed and with a lot of pride.

The opposite is also true: if your endeavor did succeed, you'll probably remember the journey with the sense of "of course deep inside I always knew this was going to be great" even if in fact you didn't believe in what you were doing.
