Like some of the other comments in reply to yours, I usually focus on a technical issue that stumped me for a long while - and then a change in perspective allowed me to solve it, or understand the solution offered by someone else. It's good to deconstruct what you got stuck on once you know the fix, because then you recognize what led you astray in the first place. (((imo)))

I think this question relates to personal growth and overcoming show-stopping obstacles with retrospective analysis? Something something smart-person-speak.
