Remember, you're never too old to enjoy the hobbies you love, and you shouldn't feel ashamed for loving them. Hobbies don't have to be productive or teach you anything, either. And hobbies aren't a waste of time if they don't offer those things. The most important part is that you genuinely love the hobbies you indulge in and they make you happy. You participate in those hobbies, not them. So, don't let other people shame you or put you down for doing the things you love.
Don't compare other people's productivity and progress to your own. Both are going to be different for different people. Don't feel bad because you're seemingly not accomplishing as much as others. We all have to navigate life in our way, at our own pace. Do that in a way that's comfortable and right for you.
