The 2 and a half years of my life and enormous amount of money I've wasted on a degree I hate back.
Failing that the ability to make the right decision for once.
You did ask
I am going to sound like the old man I am saying this, but I suspect you are in your 20s, correct?
No education is wasted, degree/certificate or just taking random classes. Lifelong learning can be one of the joys in life, and sometimes it costs money, sometimes it's free. I loved the free education, or learning, which was regarding computers in PC and Mac clubs even though I am a certified technician. You can never know too much.
Sometimes education is only somewhat expensive and I went to public junior colleges and 4 year universities, and only finished one out of four I attended, but I learned a lot and made a lot of friends for life.
And sometimes education is expensive and I did private universities and grad school, a PhD program with years of prereqs, an MA program, an MS program, law school, accounting school, and only finished a couple of those. I spent a pile of cash on this last set of schools but I would never trade it for anything. Many years later, I paid this all off and no school loans or related credit debt left. I just have one more degree I want and one more certification (accounting related) that I am aiming for.
When paying off a program of study, or degree, or trade school, or whatever, you won't see instant payoff right away. But when you are done paying off those loans, you will get this feeling that it was worth it anyway. You only live once. Sometimes the value in an education, or picking that field, is to find out what you don't like. It's a lot better than entering a field blindly, and getting stuck in it, hating every second of it, and spending thirty years there.
