The body achieves what the mind believes.

Man is by nature a reasonable being, but animals, other than man, are by nature instruments of brute force.

For beautiful eyes, look for the good in others; for beautiful lips, speak only words of kindness; and for poise, walk with the knowledge that you are never alone.

Our scientific power has outrun our spiritual power.We have guided missiles and misguided men.

It's not about being perfect, it's about being better than you were yesterday.
