I guess the key here is that this list is based on principles and not just a list of activities I would consider advantageous to have done in some sense or another. Those principles ought to be chosen as to align with my convictions and expectations from life. So you could say that I know that this list is the intersection of things I consider worthy doing (and immediately have a well-formed reason for their worthiness at the back of my mind) and recreation. When a moment for recreation has come, there is nothing that makes me question whether I should do something from the list or not because I am reassured that I have thought of this sufficiently in advance to determine the best for me.
