This is probably what most people call "perfectionism". I myself have this... "curse", if you want. It's perfectly normal to think that every piece of your work is not the best thing, cause by doing it you get a tiny little better, which for perfectionists is enough to look back and judge strictly. Learn to accept some little things here and there once in a while just to maintain normal levels for free time and sanity. :)
