The happiest people on earth are down to earthPeople who are down to earth are authentic. They see others for who they are. There is no judgment in their perspectives. Unlike others, they don't criticize or complain. They focus on good qualities and not on the negativity others are carrying inside them. They don't join the masses or try to be popular among them. For them, standing for the right is more important than voting for popular. They value life and are grateful to it. Thus, they believe in accepting things rather than expecting more.
What makes them down to earth is that they are free from the ego which is the main cause of jealousy, hate and discrimination. They look at things from a higher perspective. Humbleness is their main trait. When a person has so many wonderful qualities and has learnt to live and love life and be grateful to every second of it, how can he be devoid of happiness?
