Well, you may be the one of the few that like improving the same project, day after day, until it's good enough to get some money out of it.

Most people get bored, and will only create something for themselves if they act responsibly after a while. Unless what you call "responsible" is working for other people, instead of the more usual "hey, I don't want to do this right now, but I'm doing because I know it's good for me" meaning.
