When a hobby becomes work it becomes a stressor, in which case it’s time to dump it. I’m of an age where I no longer do things “because I have to.” I do things because I want to.
Sure, there are times when one must follow through on goals and targets because we need this to stay grounded and to challenge ourselves, but there is no good reason to continue a pursuit if it no longer has an upside (keeping in mind the upside might be on the other side of discomfort). This is even more the case when it is only a hobby.
Hobbies are supposed to be fun, if you’re not enjoying it, fuck it
