Step 1 - Take the full amount of your neuroses (you heard me...all of it) and unleash it into a notebook, or better yet, in a blog post for all to see.
Step 2 - Sleep on it. Don't look at it again, don't judge it, don't go there. Just sleep on it.
Step 3 - After 24 hours, go back and read it...yes, all of it. Every word, and if need be, read it again.
Just three easy steps and that should be quite enough to embarrass (perhaps even shame) you into quickly changing your tune.
