Leon Uris said this quote
“ This was what I came to found. The conquest of loneliness was the missing link that was one day going to make a decent novelist out of me. If you are out here and cannot close off the loves and hates of all that back there in the real world the memories will overtake you and swamp you and wilt your tenacity. Tenacity stamina... close off to everything and everyone but your writing. That s the bloody price. I don t know maybe it's some kind of ultimate selfishness. Maybe it's part of the killer instinct. Unless you can stash away and bury thoughts of your greatest love you cannot sustain the kind of concentration that breaks most men trying to write a book over a three or four year period. ”
