"Happiness comes from achieving goals" I achieved plenty, but realized late in college that constantly studying was a defense mechanism for depression and loneliness. It's my biggest college regret. I even think that if I had studied less and spent more time getting to know housemates and classmates, I would have been happier and more relaxed, leading to higher grades. Sharing life with others is a reward in itself though, which took me a while to understand.
