Read less and regret the famous saying.

Reading without regret is a famous aphorism:

Young people don't know how to study hard, and old people regret studying late.

Black hair doesn't know how to study hard early, and white hair regrets learning late.

If young people don't work hard, old people will be sad.

When the book is used, I hate it less. It's not difficult. Let's talk about it later.

Don't be idle, it's white and sad.
