When you have a community, it makes your goals a little more attainable. Starting new habits, changing a lifestyle is difficult when there are no people coming along side you to encourage you along the way. When you have a community, you have people who have the same goals as you who can push you when you feel less than motivated. Dr. Vincent and John Levell both note that having a community also means that people are relying on YOU to keep them accountable as well. Staying healthy is possible without people, but people make it so much easier.
