One of the most important things you can do in your career is generate value for your employer far in excess of what you receive back. You can talk your way into a high-paying job, but you will not remain there unless you provide more than you take.

Do not allow others to control or influence you.

Everything is negotiable, and thus it is important that you choose your negotiations wisely. First, judge your negotiating environment and determine when you can and cannot negotiate; in many important matters, negotiating may actually work to your detriment.
