One thing I have tried is hiding all my saws, drills, etc. when doing anything I know won't require them under "normal" circumstances. That way, when something goes awry (which is sure to make me mad) I have cool-down time while looking for the saw/drill/5 lb hammer/etc. to fix what went wrong. Too many bad things can happen when you are p.o.'d, working in a cramped area, and have a tool of mass destruction in your hand.
