How much time do you spend on setup now compared to before the mishap? I blew up a router bit once by not checking the feed rate. Now I double-check everything, even if it feels slow. It's not just about wood, it's about trusting your process. Mistakes like that stick with you, make you better.
My old table saw setup used to take maybe two minutes because I just wanted to start cutting. After ruining a whole sheet of plywood with a bad fence alignment, I spend a solid ten minutes now checking measurements and square. I used to think that was wasted time, but watching good wood turn into scrap changed my mind completely. That careful setup feels slow but it means I never have to redo a cut, so it actually saves me hours lol.
Yeah, when you said mistakes stick with you, it reminded me of when I rushed a paint job without sanding first. The whole thing peeled in a week and I had to redo it from scratch. Now I never skip the boring prep work, it saves so much time later.
