Oh interesting, I read an article a while back about some barbers who totally avoid thinning shears. They said it can make hair look frizzy and weak over time, especially on certain hair types. Your pointed snip method sounds like it gives that piecey texture without wrecking the hair's health. Makes a lot of sense when you put it that way.

Consider whether getting too sharp at spotting details makes you second guess everything. You might start fixing things that aren't broken just because they look a bit odd. I've caught myself staring at a perfectly fine power supply for ten minutes over a scratch. That moment of saving a board feels good, but so does not wasting time on stuff that works. How do you know when you're being thorough versus when you're just inventing problems? Getting good at this seems to need a built in off switch for your own eyes.

Oh man, my own stubborn refusal to follow recipes once led to charcoal toast and a very angry smoke alarm!
