Writing is like sex. First you do it for love, then you do it for your friends, and then you do it for money.
The inordinate love of money, no doubt, may be and is 'the root of all evil,' but money itself, when properly used, is not only a 'handy thing to have in the house,' but affords the gratification of blessing our race by enabling its possessor to enlarge the scope of human happiness and human influence.
Love is like water. We can fall in it. We can drown in it. And we can't live without it.
