Simplicity is the ultimate sophistication.

I have been impressed with the urgency of doing. Knowing is not enough; we must apply. Being willing is not enough; we must do.

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

Love shows itself more in adversity than in prosperity; as light does, which shines most where the place is darkest.

I love those who can smile in trouble.

Study without desire spoils the memory, and it retains nothing that it takes in.

The knowledge of all things is possible.
