Oh yeah, I make myself crazy sometimes because I have to keep checking posts over and over before I send them. And then, once posted, I'll read it over, find something I don't like and edit it again if possible. If it's not possible to fix a post that I sent then I'll mull over it for hours, feeling bad because everyone will think I'm an idiot.
FYI: this post was re-written 3 times, checked 9 times and I looked up the word 'mull' to make sure it was in proper context. And, I'm still not real happy with it.
