As someone who doesn't hold a university degree, I'm a great example how successful you can become without any higher education. I was able to achieve my goals by creating an online business. It's what inspired me to start this website so I can help others do the same.
I think working online is a great option for anyone, but it does take time to gain momentum. Until your website takes off, you still gotta eat, right? The jobs in this archive are great options to look into, especially since some come with excellent benefits and retirement.
There's a pretty diverse list here. Some jobs are pretty obvious, like photographer, while others are ones you may not have thought of like dive welder. Scroll through and see which ones might be available in your area or worth investigating further.
