This is not a list of recommendations. It is a list of things that left a mark on me, for reasons that are probably only mine.
music
Lo-fi, almost always while I work. It gives me a rhythm without asking for attention.
food
Cooking. It is the one part of my day where the result is immediate and I cannot automate any of it.
movement
Padel and the gym. I need the physical version of a problem to solve, or my head does not settle.
travel
Going somewhere and staying long enough to stop being a tourist.
