this is very true!
Nothing needs to be a finished forever product, unless that's what I intend to do with it. I have plenty of work complete, yet I can spend a few more hours adding bodies or placing these characters into environments that better suit a story line. It's quite normal. They certainly don't draw Homer Simpson from scratch for each frame needed to finish an episode of The Simpsons. Drawings get reused constantly.
