Maybe that is the whole point of hobbies too? The main focus is that they give you pleasure. That you enjoy it. Who said you have to be good at it? Play the guitar badly, draw ugly portraits, and so on.
There is the related idea that your hobbies need to be going somewhere. Just like with side-hustles, your very being needs to be directed to some productive goal. But that is a lie.
Your enjoyment is important. In fact, your enjoyment may be the whole point of working hard. So if you have a hobby you like, just keep at it.
