My youngest son, Jon, is just beginning his first real job. I'm excited for him, because I know how many valuable and important lessons he's going to learn while working a summer job. I also like the idea that I don't have to pay him an allowance for the next few months. Maybe now I can get that Lexus.

But I'm nervous for my son, too. It's sort of like how I felt when he started school. I was worried that we hadn't taught him everything he needed to know to cope with the rigors of first grade -you know, like being able to cut his fish sticks at lunch and stuff like that. And now I'm concerned that we haven't taught him everything he needs to know about working for an employer.

There's at least one major difference between now and first grade, however. In first grade, he would listen to his parents, like he believed that we knew things that he didn't.

Now? Not so much.

So I'm going to write some advice for him here. If any of you see Jon, please feel free to share it with him. Maybe he'll listen to you.

If you're going to do a job, do it right. The easiest way isn't always the best way. Shortcuts through hard work almost always lead to more work -and harder work -for someone, somewhere down the line. Learn to savor and appreciate the joy that comes from doing a job well. Like my Dad used to say, "The only thing that's good half done is a steak."

The customer isn't always right. In fact, the customer may be dead wrong from time to time. He or she may even be rude and surly and have bad breath. But the customer always deserves to be treated with kindness, courtesy, patience and respect. Without them, your boss doesn't have a business, and you don't have a job.

Always do what's expected of you. Then do a little more. Bus an extra table. Wipe down another counter. Straighten another rack of clothes. I don't know of one person who was fired for doing more work than they were paid to do. But I know a lot of people who had some wonderful opportunities come their way because an employer was impressed by extra effort.
