no, you should use debt to your advantage. credit ratings are important and the easiest way to improve them is to demonstrate you can manage debt ie, by paying a card off in full each month like the OP does. if you dont, it makes things like borrowing money when you really need it much harder to do.

Teaching some one to manage money, is better than teaching them to manage debt.
"Hey, I managed to save up some money recently, you wanna go parachuting or some thing this weekend?"
"Sorry mate got no money, I having to bust my ass all week to pay off this debt"
Hmmmm
