Authenticity is about imperfection. And authenticity is a very human quality. To be authentic is to be at peace with your imperfections. The great leaders are not the strongest, they are the ones who are honest about their weaknesses. The great leaders are not the smartest; they are the ones who admit how much they don't know. The great leaders can't do everything; they are the ones who look to others to help them. Great leaders don't see themselves as great; they see themselves as human.

The primary ingredient for progress is optimism. The unwavering belief that something can be better drives the human race forward.

Knowledge is understanding based on what has been studied and learned. Wisdom is understanding based on what has been felt and experienced.

Don't give to get. Give to inspire others to give.
