“You don’t delete a bad habit, you build a new, better one. You feed this new habit, over and over,” he tells me. He draws a new line, this time parallel to the first clump of lines, and thickens it with more and more strokes of his pen. The new thoughts clump, layer by layer, and eventually create a habit that is stronger than the old one. You build habits that trigger the comfort system, instead of the threat system.
