Productivity is achieved through what you do, why you do it, and how you do it—all internal choices that you make yourself, and all of which are addressed in the life plan.
The life plan gives you a means of prioritization in every scope of your life by giving you a mechanism for ranking the importance of different demands on your limited resources. By assessing the impact of different options on your purpose, goals, or tasks, in reference to other choices, you can systematically choose what is best. Each of these choices is a question of prioritization.
Great confidence comes through living this way; at any time you will know that your present state of choices best reflects what you truly believe will most directly lead to what is of greatest value to you. You will be free from the worry that you aren’t pursuing the best course, because you will always have a detailed case for why you are. When you know you are doing the best things, you are free from the anxiety caused by not being able to do all things.
