Never put off till tomorrow what you can do today. 今日事今日毕, 勿将今事待明日。
No hand can make the clock strike for me the hours that are passed. 光阴如流水，一去不复返。
Seize the day, for fleeting youth never returns. 光阴勿虚度，青春不再来。
Those that make the best use of their time have none to spare.
充分利用时间的人不会有余暇。
What I do today is important because I am exchanging a day of my life for it.
我今天做的事情很重要， 因为我为它付了一天的代价。
Every flow has its ebb. 潮有涨落日，人有盛衰时。
Youth and white paper take any impression. 青年犹如白纸，可以打上任何印记。
Time is the father of truth. 时间是真理之父。
Time and tide wait for no man. 时光如逝水，岁月不待人。
As every thread of gold is valuable, so every moment of time. 一寸光阴一寸金。
An hour in the morning is worth two in the evening. 一日之计在于晨。
Time dresses the greatest wounds. 时间能愈合最大的创伤。
To save time is to lengthen life. 节省时间就是延长生命。
If you want your dreams to come true, don’t sleep. 要想梦成真，少睡多用心。
Make hay while the sun shines. 趁着大晴天，赶紧晒饲草。
