Like you told me, focus on the positives. Act as if... You are doing great. Something I'm going to try is to write down the small things that bother me and hide them for a week, then take them out and see if I can just throw them away. That way, I don't have to worry about them for a week, because I've put them away, rather than just dropping or ignoring them (which doesn't work very well for me). I expect that in most cases, I'll just be able to toss those little bits of paper.
Whoo hoo!
