The quality of your thoughts determines the quality of your personal character.

Let your desire for truth transcend all minor considerations. Ignorance is invariably confident. The man of knowledge learns to realize his own needs. Be honest and severe in your self-appraisal. Learn the art of learning, and you are well on the way to achievement. True greatness is reflective, not assertive.

Make your judgment trustworthy by trusting it. Cultivate regular periods of silence and meditation. The best time to build judgment is in solitude, when you can think out things for yourself without the probability of interruption.

To every problem there is already a solution, whether you know it or not. To every sum in there is already a correct answer, whether the mathematician has found it or not.

Vigilantly guard your mind against erroneous and destructive thought as you would guard your house against burglars and assassins.

Books are ever available friends, ready to serve you at will.

Cheerfulness has a directly beneficial influence upon health.
