You should think of your purpose as a challenge that you must grow to overcome. Many hero movies have a training montage, because one critical aspect of a good story is a challenge that the hero must grow to become able to overcome.
Your life plan should be a healthy mix of things you are doing already and new or expanded qualities that stretch you. If your qualities don’t require growth, you aren’t aiming high enough.
You will use these qualities throughout the rest of the life plan to implement those qualities in the goals you set and the tasks you accomplish daily to align with them.
