knowledge · intellectual

Children learn more from what you are than what you teach.

In my view, everyone should have intellectual hobbies as well as an interest in physical activities.

In terms of intellectual hobbies, I really like learning Chinese characters.

In adolescence, I hated life and was continually on the verge of suicide, from which, however, I was restrained by the desire to know more mathematics.

Learning new information can make people happy.
