Be the change that you wish to see in the world
Take things always by their smooth handle
Give me six hours to chop down a tree and I will spend the first four sharpening the axe
We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light
Therefore, it is necessary to be a fox to discover the snares and a lion to terrify the wolves
Every man must decide whether he will walk in the light of creative altruism or in the darkness of destructive selfishness
