I wish I hadn't changed my college major from psychology to slavic languages. I could read and write Russian and Polish very well, but when it came to speaking the languages, my pronunciation was terrible. I thought if I stuck it out my pronunciation would improve, but it didn't. Now I have a masters degree that is of no use to me and $60,000 of student loan debt. I also have a low income job. I'm pretty sure that if I had stuck with psychology I would be better off than I am now.
