Aside from often being stinkers, pilots can suffer from the "not-invented-here syndrome, " as Levin calls it: the perception that once something is damaged or didn't work, it cannot be resuscitated elsewhere.
And I remembered back for decades during the older solo concert days, pre-chronic fatigue syndrome, playing 20 minutes and thinking, I wish I could stop here because this is so perfect but it's only been 20 minutes.
