Writing a Novel: One Step at a Time

Annie Dillard wrote this passage in her book, The Writing Life:

You climb a long ladder until you can see over the roof, or over the clouds. You are writing a book. You watch your shod feet step on each round rung, one at a time; you do not hurry and do not rest. Your feet feel the steep ladder's balance; the long muscles in your thighs check its sway. you climb steadily, doing your job in the dark. When you reach the end, there is nothing more to climb. The sun hits you. The bright wideness surprises you: you had forgotten there was an end. You look back at the ladder's two feet on the distant grass, astonished.
