As you regularly revisit your document, you are going to find apparent ways to make it better. The easiest changes to your life plan will be additions. Sometimes, you’ll see obvious elements that need to be removed. You’ll also see opportunities to edit or combine existing components.
The best way to know when to change any part of your life plan is to live it fully. While you execute, pay attention to any emerging evidence that suggests that the understanding has changed. If the understanding you used to generate your purpose, goals, and tasks, and which you used to prioritize your tasks has changed, you should modify these things accordingly and instantly.
During planning sessions, revisit what you are doing and have done since the last planning session. Ask yourself why you did what you did, and how well it matched the intended result. If there is a gap between what you intended and what actually happened, what lessons can you extract from the difference? What caused the results? What improvements might be made in the future? What can be done to continue to benefit from positive results? If the task is still in progress, what changes are necessary to draw your actions closer to the intended result?
