- 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.

> be confident enough to start purging negative people

Except at 18 it's often your own raging insecurities that instantly label people as bad. More so, the main thing to tell my 18 year old self would be to just relax and open up around people who knee-jerk make you feel insecure - athletic, good looking people, really smart over-confident people, attractive women, etc. I put up all sorts of defenses when I was younger, and I paid for it, even now moving into my 30s. It's obvious now I could have easily befriended these people, or dated others, if I had just relaxed and kept my wits about me.

Want to second the drinking/bar/club/happy hour comment. It turns out that drinking is a surprisingly cheap hobby, but as mentioned it has little return.

At about 24 I consciously ended that period of my life. At 27 I have my scuba certs, pilot's license, a piano that I'm finally learning to play, a hang glider, a 4x4 which I used to take off road regularly before I got all the other stuff, etc. These have even led to several related career opportunities.

The only caveat is that these things do take money and time, and you will need strike the right balance with work. If you find you don't have enough time for something, cut your losses and focus more on what you do have time for. It's probably more important to you. I'm only just now selling the 4x4 ...
