The Zen of aircraft maintenance
A philosophical response but works well with all difficult tasks: make yourself as comfortable as possible first. Used to work with an old time IA who in my words would “feather his bed” before a difficult task. The 10 minutes he took to make sure he was comfortable and had everything needed at-hand, paid huge dividends. He was also the guy whistling while we were all cussing and his work never needed to be done over again.
