9. Choose cash or credit card.
选择用现金或信用卡。
Some people find it far harder to spend actual physical cash; other people find that paying cash makes a purchase seem trivial, even when the dollar amount is high. Know whether you're more inclined to overspend with cash or credit cards--and leave that payment method at home。
有的人购物时，如果是付现金，就觉得不舍得买了;而有的人相反，花现金让他们感觉买东西只是小事情，不管那东西有多贵。知道是现金还是信用卡更容易让自己乱花钱，然后，舍弃那种付款方法。
