From Less by Andrew Sean Greer.

“What was it like to live with genius?

Like living alone.

Like living alone with a tiger.

Everything had to be sacrificed for the work. Plans had to be canceled, meals had to be delayed; liquor had to be bought, as soon as possible, or else all poured into the sink. Money had to be rationed or spent lavishly, changing daily. The sleep schedule was the poet’s to make, and it was as often late nights as it was early mornings. The habit was the demon pet in the house; the habit, the habit, the habit; the morning coffee and books and poetry, the silence until noon. Could he be tempted by a morning stroll? He could, he always could; it was the only addiction where the sufferer longed for anything but the desired; but a morning walk meant work undone, and suffering, suffering, suffering. Keep the habit, help the habit; lay out the coffee and poetry; keep the silence; smile when he walked sulkily out of his office to the bathroom. Taking nothing personally. And did you sometimes leave an art book around with a thought that it would be the key to his mind? And did you sometimes put on music that might unlock the doubt and fear?

Did you love it, the rain dance every day? Only when it rained.”
