I have always been fond of the West African proverb "Speak softly and carry a big stick; you will go far."
Oyster Bay, New York, USA
Believe you can and you're halfway there.
People don't care how much you know until they know how much you care.
Nothing in the world is worth having or worth doing unless it means effort, pain, difficulty.
Speak softly and carry a big stick; you will go far.
Our patience will achieve more than our force.
Let us speak courteously, deal fairly, and keep ourselves armed and ready.
