Yes, it is great when a "recipe book" is available to help support a decision-maker in the tasks that lie ahead; knowing you are supporting/arguing for the decisions made by your loved one. But keep in mind that directives/wishes don't always cover all circumstances and what if's. The conversation (s) had and experience in knowing how your loved one lived and defines quality of life is priceless. In any scenario, to have played such an important role in an individual's life to have been trusted with this task is a gift from the heart- very rewarding.
