We don’t go to the gym expecting to put on 20 pounds of muscle in a single, day-long workout. Instead, we do several short workouts a week, spread out over months. Our bodies need time to heal; our muscles time to grow. And the same goes for that muscle inside your skull. When trying to develop a new skill, the important thing isn’t how much you do; it’s how often you do it.
Make no mistake, the goal isn’t to do avoid having to practice every day; it’s to make the repetition manageable so you can introduce new material every day. It’s about staying interested and excited about what you’re learning.
