I can calculate the motion of heavenly bodies, but not the madness of people.

Sometimes you put walls up not to keep people out, but to see who cares enough to break them down.

Strong minds discuss ideas, average minds discuss events, weak minds discuss people.

If you earn your bread well, there will always be people around you to apply butter.

If you treat people right they will treat you right - ninety percent of the time.

I no longer listen to what people say, I just watch what they do. Behavior never lies.
