Do you have a course or anything I could learn?

I’d recommend FutureLearn for free courses on all kinds of cool things! If you’d rather an independent-study kind of thing, set yourself a goal and hit up your local library!

I personally am learning how to safely practice Witchcraft, along with learning German, keeping up with my 4 core classes (over the summer so I don't fall behind), and stop motion animation with Gacha Club. But everyone's different, so I recommend thinking about what interests you and what you're good at, and work on branching out from there.

Definitely, jump on Coursera and take a looks at all the free courses available.
