What is the antonym of people who don't waste their youth?

The antonym of "people don't waste their youth" is "teenagers don't know the taste of sorrow"

"People don't waste their youth" comes from "Poems with the Garden" by Yuan Mei, a famous writer in Qing Dynasty: "Heaven gives birth to talents because of works, and people don't waste their youth." This sentence means that there are many talented people in heaven because someone wants to write. When people are young, they must do something meaningful and elegant, instead of being limited by etiquette, otherwise they will fail their beautiful youth.

"Teenagers don't know the taste of sorrow" comes from the Song Dynasty poet "ugly slaves, trees are in the middle of the mountain road", and the whole poem is:

Teenagers don't know the taste of sorrow and fall in love with the floor. Fall in love with the floor and insist on giving new words.

Now that I know what it's like to worry, I want to talk about it. I want to say I'd better have a rest, but I said it's cold and autumn.

When I was a teenager, I didn't know what sorrow was. I liked to climb tall buildings when I was free. I like climbing tall buildings, but I have to say that I am worried that I can't write new words. Now that I have tasted sadness, I wanted to say it but didn't say it. Want to say sorrow instead of sorrow, but say "autumn is crisp!" " "

Extended data:

People don't waste their youth.

Don't be idle, it's white and sad. A lazy youth, a lousy age.

It's a long line from Yuefu poetry, which means it's useless to be sad when you are young and strong. It is used to warn us to work hard while we are young, and not to achieve nothing when we are old, leaving only sadness and regret.
