Being connected to life is what makes it truly living and not just passing through this world as if it were nothing.
The nine points are the right ones, many of them I apply, I will mention gratitude as something excellent that takes away the negative and learning from the right people, those mentors you mention, smart people, people who not only talk but do and I can see the results and the consistency in their life.
Another thing I thought of when I was reading the list is the importance of being authentic, genuine, being yourself, doing what you love to do and seeing in it all the details that make life so beautiful and special, because there is only one life... then well... there are other things.
Most people ar by as authentic as they think they are, there's so much influence from external sources that people generally don't have an individual and unique thought these days.
It would be necessary to live isolated from everything, far from the cities, perhaps the means of communication.
