3. Learn early on to balance work and the rest of your life. Hard-headed people may insist that work comes first, second and third. Good for them, that's their choice but be warned it's a mistake to put your work before the rest of your life. Seek to both find and implement a balance that lets you find love, have a family, see your friends, be involved in hobbies and volunteer pursuits, have down time, travel, and so forth. All those other things that go to making up you. Work wants your soul but you still own it and don't have to oblige.
