There is a brief moment when all there is in a man's mind and soul and spirit is reflected through his eyes, his hands, his attitude. This is the moment to record.
~ Yousuf Karsh
I've also seen that great men are often lonely. This is understandable, because they have built such high standards for themselves that they often feel alone. But that same loneliness is part of their ability to create.
If there is a single quality that is shared by all great men, it is vanity.
