Never use a credit card for credit. The only kind of credit， or debt， that is acceptable is debt to acquire something whose exchange value is extremely likely to increase， like in a home. The exchange value of most things diminishes or vanishes the moment you purchase them. Don’t be in debt to losers.

客户满意度应该始终是每个决策的核心。
