I have three credit card, they all work for me.

But I find the truth is that credit card make people spend more money for consume, it is risk for life.

after some month, I find I don't have enough money to return the money for bank, because I spend a lot of money for shopping, but I never in this case before.

So people must have a clear thought to use the credit card, you must control yourself about money.

What is your experience?
