The Golden Rule
As a network administrator, you're vital to the success of your organization. Consider all of the people within your company who rely on the technology you support. Your attitude, aptitude, and level of professionalism impact those same people.
If you want to find success, admiration and respect from the people you serve, follow The Golden Rule: Treat others as you want to be treated.
Technical leaders are superior to mean nerds. Now that's a bumper sticker for my car.
