At night, when the objective world has slunk back into its cavern and left dreamers to their own, there come inspirations and capabilities impossible at any less magical and quiet hour. No one knows whether or not he is a writer unless he has tried writing at night.
A man will not roll in the snow for a stream of tendency by which all things fulfill the law of their being.

He will do these things when he is in love.
