Do you remember how old Ford was always writing how Conrad suffered so when he wrote? How it was un metier de chien etc. Do you suffer when you write? I don't at all. Suffer like a bastard when don't write, or just before, and feel empty and fucked out afterwards. But never feel as good as while writing.
