How to be happy. Love Agape

The happiness - this is one of the greatest mysteries of mankind. Each of us is more than just try to be happy, and if not impossible - then convince yourself and others that there is no objective happiness in nature or everyone has it different. Hence the confusion - because unhappy people try to teach how to become happy based on their experience. One says - "The secret of happiness is..." another - "The essence of happiness is..." Everyone wants to find the secret of happiness... but not all are successful.
In fact, all people are not that different. We all need one for breathing - oxygen. And in order to be happy and make others happy we all need the same thing!
