The way to rock oneself back into writing is this. First gentle exercise in the air. Second the reading of good literature. It is a mistake to think that literature can be produced from the raw. One must get out of life...one must become externalised; very, very concentrated, all at one point, not having to draw upon the scattered parts of one's character, living in the brain.
