11. Writing
If you’re good with words, writing can be more than just a hobby! You can actually earn money by writing articles or blog posts for various websites. You don’t need any previous experience to start writing, although your first gigs may not pay all that well. But once you get a few clients, with a great portfolio you can find more and more writing jobs. It’s great because you can work from home/dorm, and you can work whenever you want. There is plenty of work for writers so it shouldn’t be difficult to find your first job.
