(1) Advise people to cherish time.
I don't know how to study hard early, but I regret learning late.
It is easy for young people to learn, but difficult for old people. Every inch of time is an inch of light.
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
