On the Project Happiness website there is a page about happiness circles. These are a community driven support group to help connect like-minded individuals and spreading happiness and all of the traits that entails. The first tier is about growing happiness within yourself through the core trails like mindfulness, gratitude, physical wellness, altruism, empathy, and meaning.
Once you have gotten to the point where these are a part of your life there is tier 2 which connects people based on positive beliefs, social support, and regular practice. Community is one of the most effective ways to help people make progress in something since you have constant support and encouragement. At Project Happiness this is a big part of the process as well.
