A hobby grows harder to enjoy when every session must produce something worth showing.

An audience changes what an activity is for. Once each attempt has to be photographable, the failed experiments stop being allowed, and a hobby quietly acquires the standards of work without any of its compensations. You start choosing the projects most likely to succeed rather than the ones you are curious about. The pleasure was in the not knowing, and that is the first thing to go.

Give yourself a few sessions this month that nobody will see. Work on the thing you would be embarrassed to show halfway through. If you usually post, notice how the choice of project changes when you decide not to.
