I also noticed there's a very risky delay in the subjective monitoring/signaling loop which maintains conscious interest in a hobby.
If the original, reliable interest signal isn't really there anymore, but one acts as if it still is, the result can be a burnout/workaholic effect with hobbies, and it can be more devastating there than at work.
The mind will additionally tend to try to switch between blaming self and blaming hobby, as it reconciles precious identity and social signals and so on.
This in spite of the fact that it could just be that the person who previously enjoyed the hobby didn't take enough breaks.
Aren't these also hobbies, just not very esteemed ones?
seems there are some similarities between the two. both hobbies and addictions involve engaging in an activity, seems a key differences lie in the level of control, balance, and well-being.
