Bullet Method worked for me for a long time. The lack of flexibility for shifting priorities made it difficult for me though. And the fact that items on the list didn't stop being to-do items, they just got pushed aside for "that's easy, I'll do it now" items is what got me. Also getting laser focused on things that don't matter. See woodworking and garage organization and buying the M and......this sounds familiar. Go off to do one thing and get 3 accomplished while completely forgetting what I was supposed to be doing.
Wife is always annoyed because she'll tell me something, and I'm listening/process it at that time, but then it zooms away, off into the abyss, cause my mind suddenly gets lost thinking about other things.
Quite distracting at work especially. The second something doesn't stimulate my brain, off it goes thinking about other things.
