There are times when things must be done for survival, sure. When your hobbies and interests must be because you get something out of them. When you’ve got mouths to feed. But it doesn’t need to be like that, and you don’t even need to be good at things.
You can sing badly. This is the only way you will ever learn to sing well. Same goes for dancing. I had two left feet, and began practicing. Now I am marginally less bad at dancing. Drawing. Archery. Working out. Programming. Creating anything. These things are all much the same: we start in some degree of bad to mediocre. That is what your talent is. It decides if you start bad or start mediocre.
In reality, this talent is likely composed of formative experiences you had earlier in life, and is itself just built-up skill. That does not devalue it. Quite the opposite, it encourages further learning by showing what it can accomplish. But even if you lack this talent, you can reach that point with diligence.
But it need not even be to reach a point. You can sing badly in your kitchen. Your dance moves can be uncoordinated swings while you clean your bedroom. You can crack your voice when you sing in the shower. You are human. You are experiencing life. That is enough. I am quite confident you will not regret doing these things when you are 80 years old.
