One cannot put back the clock

光阴一去不复返。

One hour today is worth two tomorrow.

今日的一小时抵得上明日的两小时。

One today is worth two tomorrows.

—个今天抵得上两个明天。

Procrast i nat i on is the thief of time.

拖延即浪费时间。

Take time for deliberation; haste spoils everything,

静下来慢慢想，欲速则不达。

The best time to worry is tomorrow.

最佳的忧虑时间就是明天。

The busiest men find / have the most leisure / time

最忙碌的人时间最多。

The early bird catches the worm.

早起的鸟儿有虫吃。

The early man never borrows from the I ate man.

早起三朝当一工，免得求人落下风。

The longer the night lasts, the more our dreams will be.

夜长梦多。

The morning is wiser than the evening,

早晨比夜晚有智慧。
