“Treat your discipline like a blade and the promises you make to yourself like a whetstone. Each time you keep one of those promises, you get to run that stone along the edges of your blade. You don’t sharpen that blade in a single setting. Like all good things, it takes time. It must be slow. It must be meticulous. It must be thoughtful. It must be tender. This is how you develop discipline, by keeping the promises you make to yourself––day after day after day.”
