Well, I would value my fiction career. If I seriously did not publish a book before I die, I would be very unhappy. I want to have at least 30 books out there. Here's what I wouldn't value: I wouldn't value having not ever fucked a hot girl. Or really... haven't ever found love... or would I?
So enough of this procrastination crap. I would also value having been in all the worlds that fiction can allow.
