I would stand and look out over the roofs of Paris and think, "Do not worry. You have always written before and you will write now. All you have to do is write one true sentence. Write the truest sentence that you know.
I don’t even know what I’m writing, I have no idea, I don’t know anything, and I’m not reading over it, and I’m not correcting my style, and I’m writing just for the sake of writing, just for the sake of writing more to you… My precious, my darling, my dearest!
I have thought many times since that if poets when they get discouraged would blow their brains out, they could write very much better when they got well.
Never write about a place until you're away from it, because it gives you perspective. Immediately after you've seen something you can give a photographic description of it and make it accurate. That's good practice, but it isn't creative writing.
Now as to magic. It is surely absurd to hold me "weak" or otherwise because I choose to persist in a study which I decided deliberately four or five years ago to make, next to my poetry, the most important pursuit of my life...If I had not made magic my constant study I could not have written a single word of my Blake book, nor would The Countess Kathleen have ever come to exist. The mystical life is the center of all that I do and all that I think and all that I write.
