How to write: jot down, accumulate, spread out and dispose

From long practice he could scribble legibly and inconspicuously.

After accumulating a hundred of two hundred of these notes, he would seat himself at his desk, cover the floor around him with the slips of paper, and start writing. When his invention lagged, he would lean over and pick up a slip of paper. If the paper failed to suggest anything useful at the moment, he would toss it back on the floor and pick up another. Sooner or later he would find a note which would inspire him. Once used, the slip would be crumpled and thrown into a wastebasket.

I follow the very same procedure with a notebook I carry everywhere. I often convert some of my notebook/journal entries into permanent notes for my slip box (zettelkasten).
