When you work for someone you are selling them your time. So sell them a good product. Sell them your time in the best way. Do a good job, no matter what job you are doing.
Sell your time for the most you can sell it for. Even if you only make a dollar an hour more than the rest of the workers, sell the best of you that you have to offer. Once you realize that one day you’re going to die, you will value your time more.
