You can write any time people will leave you alone and not interrupt you. Or rather you can if you will be ruthless enough about it. But the best writing is certainly when you are in love. If it is all the same to you I would rather not expound on that.
Ernest HemingwayFor a true writer each book should be a new beginning where he tries again for something that is beyond attainment. He should always try for something that has never been done or that others have tried and failed. Then sometimes, with great luck, he will succeed.
