Answer:
Thats actually up to you!
Explanation:
Right now, I am taking photography and video classes in college, but its up to your interests. If you are maybe in middle school or in a lower grade, and you are a gamer, you can start doing Twitch, Mixer, etc. streams. That is what I did, and had a couple thousand subscribers. My ex told me I spent too much time on video games, which made me delete my Twitch account. But with the money I made on Twitch, I used it for college tuition. Lets say you like animals, they have a class for vets. Wanna be a Mechanic? Theres also a class for that. It's really just up to you to look in yourself and see what your good at and if it makes you happy.
