1. Word of mouth
What I think would be the best way to live a long and happy life is not unique. The best way to teach anyone the way to be is to live and say little unless asked about it.
One of the biggest ripoffs is those who are holiday and sunday, or saturday religious nuts. By this what I mean is simple, like any other cause. To go and give lip service or just put your time in to earn the way to your heaven is a lie first to yourself. Those around you can see if you live what you believe, but you convince yourself that by doing your half hour a week you've meet the requirements.
I choose not to live my life this way. So I put out this challenge to all who read this. If your commitment is to church, charity, helping others, or an organization. This does not include yourself. Live it and share when asked, but first meet this condition. When practicing your faith link it to a physical thing like food. If you only practice your faith a half hour a week that is all the time you have to eat in the week. Since a persons faith should be the spiritual food for all people. This does not mean you need to join a religious group or order, but it does mean you have to get off the couch. It also means you have to stop waiting for other people to do what needs to be done.
So if you want to try it out it is just this simple. Measure how much quiet time you do to refill the quiet space. Then link it to food and only eat the amount of time for a week that you fill your quiet space and replenish your soul.
