It sounds hard, but daily turns out to be easier than weekly or fortnightly. If you do it daily, you don’t miss.
Daily writing. Daily exercise. Daily prayer or meditation. Daily time with the right people.
Daily accumulates by a magnitude. Low bars and high cycle-speeds will see you on your way far more effectively than the fits and starts of enthusiasm, and one day you’ll find yourself, if not at the top of a mountain, then at least on a small hill with a breeze and a half-decent view.
