Cost of education

Many years ago I made a critical miscalculation . I thought I could drop out of OSU and come back to it later. 25 years later, after several failed attempts, I am still trying to figure out how to get back. How to get that done for myself. Today as I read over the info for several different programs it was the cost that overwhelmed me. 23 to 28,000 a year? Even if I could finance it how can I earn enough after to justify spending 90,000? How does anyone? Is there something I am missing here? How can make this work?

Maybe I'll throw a benefit art auction for myself..,,
