- be confident enough to start purging negative people and situations from your life.

- Early in your career, if you ever find yourself saying "I wish I could do X, but I work to much/have already used all my vacation time, etc" - without question you should to do those things and work less. Nobody ever looks back in time (especially in a situation when they are out of time) and says "gee I really wish I worked more".

- You are about to enter the age of drinking/bar/club/happy hour culture. Sure, have fun. But remember that there is almost never any return on this investment. All that time spent in the bar (and the time spent recovering from it) costs you time that could be spent pursuing your passions, hobbies, fitness, etc. Those things return in MULTIPLES later in life.
