There is only one way to happiness and that is to cease worrying about things which are beyond the power of our will.

If what charms you is nothing but abstract principles, sit down and turn them over quietly in your mind: but never dub yourself a Philosopher.

Wisdom means understanding without any doubt that circumstances do not rise to meet our expectations. Events happen as they may. People behave as they will.

You become what you give your attention to...If you yourself don't choose what thoughts and images you expose yourself to, someone else will, and their motives may not be the highest.
