I feel the same way ...
When I wash my hands, I *have* to do the 'surgeon wash' where you soap all the way up your arm to get yourself nice and clean.
When I see a pile of CDs not piled up neatly, I fix it.
When I see that my laptop's charger is tangled up, I have to fix it. I'll drop whatever I'm doing to fix it.
I hate anything that I do that turns out half-assed.
But I don't always get this way -- thankfully.
