What makes you really happy?

Usually I like working out, spending time with my family, reading, hunting, fishing, 4 wheeling, but ever since I've been in college I just don't have time for most of these things and I don't yet know what my true passion is outside of work yet (I like to think its fitness and health, but I don't have much time to workout now). So right now what makes me happy is spending time with my girlfriend, learning new things, working out when I can. What do you do to be happy when you're super busy? What do you to be havppy when you're not super busy?
