A lot of times I find myself coming out of movies or conversations that leave me empty. I think to myself "Wouldn't I be more happy if I had just done 1,000 push-ups or read a book on Freud instead?" It seems as though this should apply not only to short experiences like a conversation but to anything we do in our life. The trick is that we need to know before and not after that we would have rather done 1,000 push-ups.
