I don't know your karma. You may have a karmic trajectory that is rich in a store of merit. So this is not advice for you per se, but just a general take on your type of situation:
When I was 25 I was living at a buddhisht center. A guy my age moved in that had been living in his pickup truck. He had been picking berries in the woods and selling them to the hippie market in town for gas and food money.
After he moved in he got a job as a bank teller. That got boring quick, so he said, "If I'm going to work in a stupid bank I might as well do it right." So he went back to school and finished his bachelor's. Then he went to grad school and got his M.B.A. He became an assistant vice president of a large American bank, made a bunch of money, and retired at the age of 35. That includes paying off his student loans. So in 10 years he went from homeless to retired because of education.
If you are doing it with the motivation to be able to practice Dharma, accumulating the materials for doing retreat also has merit and is part of the path. The hardest part of that particular path is to not end up spending the money on such things as an expansive lifestyle, and getting married.
What you don't
want to do is in a quixotic way dedicate your life to an ideal, only to find out later that your life has too many difficulties for you to see it through, and then you resent
the Dharma for your problems. That's bad, and it has happened a lot. My hippie friends that refused to get serious about work are nearing retirement age with absolutely nothing to show for it. They will have to work until they drop dead, at whatever age.
What you do is up to you. I've read your posts. You're a bright guy. Don't automatically think that getting you act together is somehow contrary to Dharma. Dharma is about developing your awareness. A secular education also develops awareness, but in a lopsided way. If you have a Dharma practice to go with it, you will have all your bases covered.

I know that to teach English in South Korea you need a college degree, fwiw.
