Life is the greatest teacher because it educates even those who really hate to learn.

The universal mission of all educators is to let the torch of knowledge illuminate the world.

It is equally important to learn from experience and from books.

Spreading knowledge is the most effective weapon for defeating ignorance.

Knowledge can be acquired by education, reading, communicating and observing, but also simply by living.

The essence of coexistence is quite simple: live and respect how others live.
