Time is money. 别浪费时间,时间就是金钱。Make hay while the sun shines. 趁热打铁。If you want to get ahead, get busy. 想要成功,就要努力工作。Work smarter, not harder. 工作要聪明,不要单纯努力。The early bird catches the worm. 早起的鸟儿有虫吃。A penny saved is a penny earned. 省一分钱就相当于赚一分钱。Seize the day. 抓住今天。You reap what you sow. 种瓜得瓜,种豆得豆。There is no substitute for hard work. 没有什么可以替代勤奋的工作。Every little bit helps. 积少成多。
