Totally get this! I was building a simple shelf and assumed all studs were 16 inches apart. Measured everything wrong and had to redo a whole wall. Felt so silly for not checking the actual building code first. It's wild how these basic things we take for granted can trip us up. I double check every single standard measurement now, even the simple ones.

Wasn't a hole saw, just a regular drill bit.

Ever spent an hour looking for your phone while you were holding it?

Totally get what you mean about the luxury tool feeling. Mine collects dust until something truly weird pops up, and then it's a lifesaver. That moment when you go from guessing to knowing exactly where the heat is coming from changes everything. It feels less like spending money and more like buying back your own time and sanity on a bad day. Having that one sure thing in your toolbox makes the tough jobs way less stressful.

Honestly, the "looked clean to me" part is the whole problem. My screen is calibrated so different, I can't trust my own eyes anymore. I just start with the numbers now.
