"Xunzi? Encouraging Learning"

Those who do not have deep ambitions do not have clear enlightenment.

"Xunzi Encouraging Learning"

A person cannot ride two horses at the same time. If you ride one horse, you will lose the other horse. Smart people will ignore all requests to distract their energy. Only concentrate on learning one subject, and when you learn one subject, you must learn it well.

[Germany] Gothic

One day it is violent, ten days it is cold.

"Mencius? Gaozi 1"

If a person's ambition is not far-reaching and his mind is not right, he will not succeed in learning.
