-"Long Songs"
This is the night for men to study.
Teenagers only know how to play, but don't know how to study hard. When they are old, they regret why they didn't know how to study hard when they were young.
-Don Yan Zhenqing's Persuasion
Young people are easy to get old but difficult to learn, and an inch of time is not light.
Before the sweet spring grass grows in the pond, the plane leaves in front of the steps have rustled in the autumn wind.
-Song Zhuxi's Poems of Persuasion/Unexpected Success
If you don't come back in the prime of life, it will be difficult to get up in the morning.
It's time for people to encourage themselves when they reach middle age. Time goes by and waits for no one.
