The reason is that I do not want to be a writer for the rich. I want to be read by working-boys and girls, and by poor students.
I offer the book at a low price. In the hope of tempting you to go out and get your friends to read it, I have made a price in quantities which will allow no profit at all. A margin has been figured to cover postage, stationery, circulars, and the cost of a clerical assistant; but nothing for interest on capital, which is a gift, nor for the rent of an office, which is my home, nor for the services of manager and press agent, which is myself.
