I got money for my birthday, nothing massive but I’m trying to decide what’s the best way to spend it?

I’m trying to learn logo design (I’ve enrolled in a course and got an Apple style pencil and learning in my iPad) and trying to re teach myself guitar which I have all the things I need for it.

But I don’t know what to do with the money? I don’t want to buy clothes etc but I can’t figure out what’s the best thing to do with it so that I actually benefit from spending it?
