— used to say that you should do the things that are most important before doing other things要事先办
I know you're eager to start shopping for a car, but first things first—you need to find out how much you can afford to spend.我知道你急着买车,不过事情要分个轻重缓急,你得先清楚自己能付多少钱。
You must set priorities and learn how to put first things first.你必须分清主次,学会如何将重要的事情放在首位。
