Writing is like prostitution. First you do it for the love of it, then you do it for a few friends, and finally you do it for money.
Ferenc Molnár (1878-1952) Hungarian-American author, stage director, dramatist [a.k.a. Franz Molnar]
Quoted in George Jean Nathan, Intimate Notebooks (1932)

Common form of a quote often misattributed to Molière. It original version actually appears to have originated with Molnar, who, when asked how he regarded his writing, answered (according to Nathan):Like a whore. First, I did it for my own pleasure. Then I did it for the pleasure of my friends. And now -- I do it for money.
