1) The most beautiful things in our world are all created by labor and the clever hands of people.

2) Only human labor is sacred.

3) I know what labor is: labor is the source of all joy and all good things in the world.

4) Love your work. No power can make people become great and intelligent like the power of labor, which is collective, friendly and free.

5) We learn to think in the process of our labor. As a result of our labor, we know the mystery of the world, so we really change our lives.

6) Labor builds people's confidence in their own rational power.

7) Time is the fairest and most reasonable. It never gives anyone more. Hard-working people can leave time for clusters of fruits, while lazy people leave them with white hair and empty hands.

8) Time is the fastest and slowest, the longest and shortest, the most ordinary and precious, and the most easily overlooked and regrettable thing in the world.

9) Youth is limited and wisdom is infinite. Take advantage of short youth to learn infinite wisdom.

1) Time leaves clusters of fruits for the industrious, but only a white head and empty hands for the lazy.

11) I jump on books like a hungry man on bread.

12) I have always hated people who plan for their own food and clothing. People are above food and clothing.

13) All excellent things are simple, and they are fascinating because of their own wisdom and simplicity.

14) Reason is higher than mind, and thoughts are more reliable than feelings.

15) Remember, always give more to others happily and take less from others.
