Doing things we know how to do well is enjoyable, and that’s exactly the opposite of what deliberate practice demands…. Deliberate practice is above all an effort of focus and concentration. That is what makes it “deliberate,” as distinct from the mindless playing of scales or hitting of tennis balls that most people engage in.

Summary of Rule #4 The core idea of this book is simple: To construct work you love, you must first build career capital by mastering rare and valuable skills, and then cash in this capital for the type of traits that define compelling careers. Mission is one of those traits. In the first chapter of this rule, I reinforced the idea that this trait, like all desirable career traits, really does require career capital — you can’t skip straight into a great mission without first building mastery in your field.

An effective strategy for accomplishing this task is to try small steps that generate concrete feedback — little bets — and then use this feedback, be it good or bad, to help figure out what to try next. This systematic exploration can help you uncover an exceptional way forward that you might have never otherwise noticed. The little-bets strategy, I discovered as my research into mission continued, is not the only way to make a mission a success. It also helps to adopt the mindset of a marketer. This led to the strategy that I dubbed the law of remarkability. This law says that for a project to transform a mission into a success, it should be remarkable in two ways. First, it must literally compel people to remark about it. Second, it must be launched in a venue conducive to such remarking. In sum, mission is one of the most important traits you can acquire with your career capital. But adding this trait to your working life is not simp
