Perfection of effort is not required, by the way. It is the consistency of attempting to work these tools that brings the progress. It’s like anything else. If I want to tone muscle, lifting a ten-pound weight a few times every day will move me toward my goal much quicker than hoisting a fifty-pound barbell once a week. Yes, it really is true: “Slow and steady wins the race.” Just try a little, every day. You’ll see.
