We perish as a result of our lack of knowledge, not money.

One who learns all he can is on the path to know all he must.

Knowledge helps its enemies, but ignorance harms even its friends.

The highest wall anyone can scale is ignorance; the tallest mountain anyone can conquer is fear.

A pen in a scholar's pocket is greater than a sword in a warrior's hand.

Learn if you want to teach; teach if you want to learn.
