Plenty of people either do those things because they want to, or because they think they can find additional social acceptance for having done them (which is really just another way of saying they want to do them). If wanting to do them doesn't apply to you, then don't. But understand what frequently befalls those who choose not to do those things.
I was a loser a few months ago. I'm still a loser, but now I can play the piano at a very bad grade 2, draw very poorly, and just about understand Japanese spoken by a small child.
Still, I'd recommend it, especially if you're a NEET like I am, since you'll be doing something with your time. I started doing these because I wanted to.
My regret is not starting earlier, since I'd be way more proficient than I am now, and probably enjoying it more since I won't have the frustrations that come with being inept at things.
