George Leonard once wrote: “Mastery is not about reaching perfection, but rather comes from maintaining a particular mindset as you move along the path of improvement in building your skills or overcoming challenges in any endeavor.” In other words, mastery is not simply achieving something great. Instead, mastery is relentlessly perusing the question "how can I get better" when you are already pretty darn good. If you do this, greatness will be the byproduct.
