I don't think I get attached to my older works. My feeling is, 'I published them, I should leave them up in case someone likes them' - because I know how upset I've been when works I've liked have been taken down/deleted/removed. If I was bold enough to publish them at one point, I can deal with cringing when I reread them now.

Sometimes I will dislike the actual writing, like turns of phrase or descriptions. (There's a bit in one of my Sterek fics that makes me physically cringe every damn time I read it.) Other times, I've come to dislike the characterization I used. When I was younger I really didn't care about the latter and would just shove my favorite characters into Situations because I could. Nowadays I'm much pickier about trying write moderately 'in character'.
