Motivation is what gets you started. Habit is what keeps you going.
The real wisdom here isn't that habits matter—everyone knows that—but rather that *motivation and habit are fundamentally different animals*. Motivation is a feeling, fleeting and dependent on circumstance; habit is a structure, indifferent to how you feel on any given Tuesday. A person training for a marathon might wake up inspired on week one, but by week fourteen, when the alarm goes off at 5 a.m. in the cold dark, only the groove worn into their routine will get their feet onto the pavement. Ryun distinguishes between the spark that ignites change and the quiet machinery that sustains it—a distinction worth remembering whenever you're waiting for willpower to do a job that only repetition can finish.
