Study and have fun. I wish I had studied more. Those helped me the most. My psychology courses and Gayle Greene's Women in Literature-where we had to read The Second Sex. Plus, the Humanities Internship my senior year.
Most careers involve involve writing, no matter what they are.
Many can't write and appreciate and pay those of us who do. And I must say, it was as much the love of humans the professors taught me as the science of psych. My senior year internship at Boys Republic began a career path. I had great psych teachers that way. Live in the dorm and make the great friends I did.
