lol I've done so much of the same stuff. Especially method 2. I do it for turning decisions into tasks. I think of it as "going down the stack". If "Decide which city to move to" is staring at me, I can add "Come up with how to decide which city to move to." That might turn into something concrete like "Go for a walk and think about how to pick which city to move to." Somehow, enough layers of abstraction can circle all the way to "put on shoes".

The hazard is yak-shaving, over-investing in the pre-pre-pre-planning, or becoming interested in epistemology. The trick is to try to have each layer be a tenth of the investment of the layer it supports or less. Can't stack too high that way.
