Without loving in our hearts, earth gets the sign of destruction and unhappiness over human being. Everyday and for full time we should take responsability for others. Thinking that each action we do, cause an impact somewhere...as a wave that goes and comes, over and over again with consequences on each way it does. A good change doesn't include what you expect from people for you, but what you do for all them...no expectations, except the desire to learn and make them happy. Here or there, doesn't matter where.
