Via A Piece of Monologue: Thomas Bernhard, from his autobiography, Gathering Evidence:

For long periods I live in isolation, isolated both in mind and in body … Subject to every vagary of my own nature and of the universe — whatever it is — I can get through life only with the help of a precise daily routine. I am able to exist only by dint of standing up to myself — in fact, of consistently opposing myself. When I am writing I read nothing, and when I am reading I write nothing. For long periods I read and write nothing, finding both equally repugnant.

And:

There are long periods when I detest both reading and writing, and then I fall prey to inactivity, which means brooding obsessively on my extremely personal plight, both as an object of curiosity and as a confirmation of everything I am today, of what I have become over the years in circumstances which are as routine as they are unnatural, artificial, and indeed perverse.
