You can refer to Harvard’s school motto:

If you take a nap now, you will dream; if you study now, you will realize your dream.

My wasted today is exactly the tomorrow that those who died yesterday prayed for.

The time when you feel it is too late is precisely the earliest time.

Don’t put off today’s things until tomorrow.

The pain of learning is temporary, and the pain of not learning is lifelong.

Learning this matter is not a lack of time, but a lack of effort.

Happiness may not be ranked, but success must be.

Learning is not everything in life. But, since you can't conquer even one part of life - learning, what else can you do?

Please enjoy the unavoidable pain.

Only by working earlier and more diligently than others can you taste success.

No one can succeed casually, it comes from thorough self-management and perseverance.

Time is passing.

The tears that flow now will become the tears of tomorrow.

Learn like a dog and play like a gentleman.

If you don’t walk today, you will run tomorrow.

Those who invest in the future are those who are loyal to reality.

Education represents income.

After one day is over, I will never come back again. Even now, opponents keep turning the pages.

Without hardship, there is nothing gained.
