Six mottos of Harvard University:

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

2. My wasted Today is the tomorrow that those who died yesterday prayed for.

3. The time when you think it is too late is exactly the earliest time.

4. If you don’t leave today, you will have to leave tomorrow. Run.

5. The drool you shed now will become the tears tomorrow.

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