You can reduce your anxiety somewhat by facing the fact that there isn't a mechanic alive who doesn't louse up a job once in a while. The main difference between you and the commercial mechanics is that when they do it you don't hear about it-just pay for it, in additional costs prorated through all your bills. When you make the mistakes yourself, you at least get the benefit of some education.
