Long, but very interesting.
I read "Zen and the art..." a couple of decades ago, and now I think I should perhaps have another look at it. What I remember most is his questioning of how someone can work in a concentrated manned on an engine with the radio going in the background. That stuck in my head, as I ask the same question myself.
The concept of a "Gumption Trap" is fascinating. I'd never heard of that, but having consulted the Wiki on the subject, I realise that I am very susceptible to those. Hmmm...
EDIT: thinking about it, I reckon the more one is a perfectionist, the more likely one is to be susceptible.
