Update: I read a study that said 70% of bullet journal users quit within 90 days

Found this stat in a research paper from a university in Portland, and it completely shocked me because our online spaces feel so active. I always believed the system had a high success rate for building habits. Does this match what you've seen with friends who tried it?

Warning: I used to fix old tube TVs by just swapping parts until something worked

Honestly, for years my repair process on those big CRT sets was basically guesswork. I'd get a unit with no picture, open it up, and start pulling tubes to test them on my B&K 467. If one was bad, I'd swap it. If that didn't work, I'd just keep going, maybe poke at the flyback with a meter. It was messy and took forever. Ngl, I changed my whole method about 5 years ago after wasting a whole Saturday on a 1972 Zenith. Now, I always start with a full schematic, check the B+ voltage first, and follow the signal path step by step with my scope. It's slower at the start but way faster to actually find the real fault, usually a bad resistor or a cracked solder joint. Has anyone else made that switch from the 'shotgun' approach to a real diagnostic routine?

Honestly, I just found out the whole 'wait an hour after eating to swim' thing is a total myth

My friend swore by a 20-second pre-infusion for light roasts and I finally tried it

My buddy Mark, who roasts his own beans, kept telling me to try a longer pre-infusion on my pour-over for light roasts. He said, 'Give it a full 20 seconds of bloom, no less.' I always did about 10 seconds and thought he was just being extra. Last week I tried his method on a new Ethiopian from a shop in Portland. The difference was huge, way more floral notes and none of the sourness I sometimes get. Has anyone else found a specific timing trick that actually changed your results?
