At the risk of sounding like a total nerd, I've never had an issue with debt and have always had good credit. Somehow, Mom and Dad got the message through to live within my means and pay off debts quickly.

Maybe it was because I saw my parents living simply, budgeting their money, balancing their checkbook, and not buying many of the big-ticket luxuries that their friends were indulging in. I can remember hearing my father say to my mother, "When you see me driving around a Mercedes , I won't be worrying about making payments." I guess I took that to heart and didn't want to worry about making payments, either.

I was the older of two kids from immigrant parents and grew up in a middle-class neighborhood. My dad was in the Navy , and my mom worked in the banking industry. My parents bought their first home when I was about 10 years old, and my mom managed the household finances.

When I was old enough, Mom gave me money management “training wheels” by putting me on her credit card account. But she didn't just hand the card to me without instructions—she taught me the basics like credit limits, balances, minimum payments, and payment due dates. And, while I didn't completely understand its value at the time, she emphasized how proud she was of her good credit rating . She said that I should try to build my own good credit by paying back my debts and always paying on time.

Now that I work in the credit card industry, I recognize the value of these lessons. And, from talking to friends, I've learned how uncommon it is for parents to give their kids the basic financial guidance I was lucky enough to get. By the time I got a credit card in my own name, I understood that each purchase I made was actually a little loan that needed to be paid back—so I really thought long and hard before using it.

Thanks to my folks, when I ventured out on my own I did so with a good credit history. This signaled to lenders that I was a good risk to buy a car or to rent an apartment. I was surprised to learn that even employers were interested in my credit rating. And, when it came time to buy a house of my own, I was able to qualify for a mortgage with a lower interest rate, which saved me a considerable amount of money.

What money management lessons—good or bad—have you learned? And who have been your teachers?
