More Than A Job
A job is a serious commitment. You spend more time working than you spend breathing, so it's a good idea to make sure you have a plentiful oxygen supply next to your desk.
Extract from the 48 Laws of Power by Robert Greene and Joost Elffers:
Law 30 - Make your Accomplishments Seem Effortless - Your actions must seem natural and executed with ease. All the toil and practice that go into them, and also all the clever tricks, must be concealed. When you act, act effortlessly, as if you could do much more. Avoid the temptation of revealing how hard you work :: it only raises questions. Teach no one your tricks or they will be used against you.
Your job is important to you. You wouldn't leave your wallet lying around for someone else to pick up, so why treat your job any other way? And don't forget, if you leave your job in a parked car in the hot sun, open the window a crack.
