If a person doesn't work hard when he is young, he will regret when he is old ―― laziness when he is young will make him regret when he is old; Reckless youth makes regretful old age; Idle youth, poor old age

We only live once in this world, so we should cherish time. We must live a real life and a valuable life. -Pavlov

An inch of time is worth an inch of gold, but a thousand dollars can't buy an inch of time.

Don't always sigh the past, it will never come back; We should improve the present wisely. We should devote ourselves to the confusing future with the firm will of not worrying or fearing.

-Longfellow

Don't sigh for the lost years, but face up to the time that has slipped away in a hurry. -Brecht \x0d When many people are wandering on a road, they should make way for the road and let those who cherish time walk in front of them.

-Socrates
