"ask yourself in the stillest hour..."

"You are directing your thoughts outwards, and that above all is what you should not do at present. No one can advise and help you. No one. There is only one way. Withdraw into yourself... ask yourself in the stillest hour of the night, 'Must I write?' Dig deep into yourself for an answer. And if this answer should be in the affirmative, if you can meet this solemn question with a simple strong 'I must,' then build up your life according to this necessity. Your life right down to its most indifferent and unimportant hour must be a token at a witness to this compulsion."
