2. Sharing

Do not be too focused on cash. Nobody can live without any money, but this is not what makes us happy. If you have enough to satisfy your basic needs, you are lucky. If you have some spare money left, there are 2 ways you can use it to stay happier. One is by using your money to promote yourself socially. The other one is to share it with others. Helping less fortunate is rewarding and gives you the feeling of importance. Contribute to the world and society.
