Time is money, but money is not time.

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

Flowers will reopen one day and people will no longer be young.

After a hundred years, youth will never come again.

Don't come back when you are in the prime of life. It is difficult to get up in the morning. Encourage in time, and time waits for no one.
