"... (1) a high enough degree of general wellbeing to enable people to devote their energies to useless activities; (2) an advanced state of social atomisation and the resultant general feeling of the isolation of the individual; (3) a radical absence of significant social change in the internal development of the nation. (In this connection, I find it symptomatic that in France, a country where nothing really happens, the percentage of writers is twenty one times higher than in Israel)…The irresisitable proliferation of graphomania among politicians, taxi drivers, childbearers, lovers, murderers, thieves, prostitutes, officials, doctors, and patients shows me that everyone without exception bears a potential writer within him, so that the entire human species has good reason to go down the streets and shout: ‘We are all writers!'”

Wrote Milan Kundera in "The Book of Laughter and Forgetting" (1979), quoted in "The write stuff: A brief overview of typomania and graphomania," a blog post by Dr. Mark Griffiths, Professor of Gambling Studies, International Gaming Research Unit, Nottingham Trent University, Nottingham, UK.

Griffith also quotes an 1896 NYT article "Bryan’s Mental Condition" (Bryan = Democratic presidential candidate William Jennings Bryan):

“The habit of excessive writing, of explaining, amplifying, and reiterating, of letter making and pamphleteering, forms a morbid symptom of known as ‘graphomania’. Some men may overload their natural tendency to write, but a certain class of lunatics use nearly all their mental activities in this occupation, to the endless annoyance of their friends, relatives and physicians”.

ADDED: I'm looking up this word after confessing to Meade that I wrote 6 1/2 pages in my handwritten notebook before 4:46 this morning, before beginning my first blog post, which was published at 5:21 a.m. The post you are reading now is the 6th of the day. And I've written in the comments too.
