Maybe you should have taken it in school when you had the chance.
I learned very little, certainly learned more just reading the books than going to class. Class was largely useless.
Philosophy helped me to think critically and find edge cases. Psych taught me about different parts of the brain and their functions. Soci taught me my professor was a giant fraud and the entire discipline was a 'solution' looking for a problem.
