If you feel like something is wrong, believe me, you can find something that is actually wrong. It isn't even difficult!
Now, if it's getting too much and you can't help it, you can channel this. Never mind what's wrong with where you're looking. There's always something wrong. What's interesting is if you can find something wrong that needs more attention. Something underrecognized, maybe an unsolved problem, or one solved elsewhere but not here. Or maybe you can notice some pattern in a problem here that helps over there.
If you are feeling very much inclined to look in the shadow of every stone, that certainly has its uses.
