Not so much motivational as guidance are:

"Never eat at a place called 'Moms'
Never play Pool with anyone called Slim, or Poker with anyone called 'Doc".

Don't criticise anyone until you have walked a mile in their shoes - then say what you like. After all you're a mile away and you've got their shoes"

"We can never obtain peace in the outer world until we make peace with ourselves."

"With realization of one's own potential and self-confidence in one's ability, one can build a better world. "

Dalai Lama
