Oh yeah I've done that. I'll go back (especially to some of very first works waaaaaaaaaaaaaaay back in 2004/2005) and went "OMFG why the hell did I think I could write?" It's nice to see that my stuff has matured (hopefully) and isn't as childish (again, hopefully, lol) as it used to be back then. Or I'll read older fics and then re-write them (like I'm starting to with 2 HIM fics).
