How do you manage your credit cards responsibly?

Firstly, I would like to emphasis that use this leverage wisely and treat your credit cards as your cash in your wallet. When purchase with credit card, please ensure that you have such amount to pay back when credit card bill arrive on the beginning of the month. Secondly, I used to monitor my credit card expenses weekly to ensure that no overspend occur. If happen then I need to inform my wife to reduce the balance expenses. Finally, my advice is pay in time because the moment your payment late. Then additional charge will be appeared on the following month.
