Be the one in charge. There’s an old truism from sales school that says you can’t shoot a deer from the lodge. The same goes for learning: you have to suit up, get out the door, and find what you’re after. Mastery, especially of complex ideas, skills, and processes, is a quest. It is not a grade on a test, something bestowed by a coach, or a quality that simply seeps into your being with old age and gray hair.
