I regret choosing the wrong major for me because it was in a field that had a lot of opportunities — but it it wasn’t my passion. I regret changing my major to a different field for the same reason — better opportunities, but still not following my heart. I’m a writer, even though I have strong math and science skills. I just lack the confidence that I can succeed with a writing career. So I go with what is safe. And it’s making me miserable.
