Great question. The feeling clearly isn't based in logic; somehow watching a TV show or playing a game (neither of which is financially productive) instead of working on "just for fun" side projects doesn't elicit the same mental response unless I really couch potato out and do those things for hours on end. That makes it a bit more difficult to work with.

Probably because of the feeling that you only have so much energy for each bucket. Watching TV isn’t taking energy from the dev bucket, but working on a fun but personal project does take energy from the dev bucket.

Of course, this isn’t how it actually seems to work - there is some truth to it for most people, but if you “overdraw” from one bucket and “neglect” another bucket, they will change sizes.
