I dropped out of a 4 year university program after 2 semesters. I had little invested at that time, and just couldn't do it anymore and realized it wasn't what I wanted to do. Went back to work full time, went to a two year tech school program, got classes and teachers that were actually interesting and engaging, paid cash the whole way through, took on no debt, and got a job almost right out of school. Now I have a career I love, make good money, and really have zero worries in life.

But in your situation, being so far in and so close to finishing, I'd count me in for a "just finish" vote. You're so close. No one NEEDS a college education to succeed or be happy in life, and it entirely tends on what you want to do with that degree, but being sooooo close like you are I'd say finish it. But I'm not one to talk, I was depressed in college and couldn't take it anymore. It wasn't me, it wasn't how I learned, it wasn't making me happy, and in the end, I didn't need it.

But this decision is entirely up to you. But like others have said, I wouldn't bank your life on the idea of "quitting money", as it's possible that is a passing flight of fancy, and that you may not want to do that your whole life. Life changes fast at any age, but even faster at your age.
