While I was developing the NewHabits-NewGoals pilot offered in January, I realized that there was a difference between what I called the major components and the minor ones. In this way, the 11 components can be neatly split into 2 groups for easier explanation.
The difference is easy to understand.
The Major components are Capturing, Emptying, Tossing, Acting Now, Storing, Scheduling and Listing. The Minor components are Interrupting, Switching, Warning and Reviewing.
The Major components are the ones that preoccupy users who find themselves at the lower belt levels. Their time is spent mostly in mastering the practices and habits in those components.
The Minor components naturally become more of a concern at higher belt levels, when users have gained a certain level of proficiency in the Major components.
Of course, this rule is not hard and fast, but only an observation that I turned into a teaching tool to help students concentrate their energies in the right place.
