Being a better person (Earth Angel) not only leads you to a POSITIVE, FULFILLING LIFE, but also BOOSTS and INCREASES your SELF-ESTEEM, promoting HEALTHY relationships and overall BETTER HEALTH. All this in turn creates POSITIVITY, creating a RIPPLING effect into other people's lives, social networks, communities, societies, and so on.
So why not be THAT BETTER PERSON to CHANGE THIS WORLD?
