You cannot open a book without learning something.

A teacher can never truly teach unless he is still learning himself. The teacher who has come to the end of his subject, who has no living traffic with his knowledge but merely repeats his lesson to his students, can only load their minds, he cannot quicken them.

On the mountains of truth you can never climb in vain: either you will reach a point higher up today, or you will be training your powers so that you will be able to climb higher tomorrow.

Learning is the only thing the mind never exhausts, never fears, and never regrets.

It is a good thing for the uneducated man to read books of quotations.

Be a lifelong student, read as many books as possible.
