Happiness is not guaranteed. In the last five years thousands of people have lost their jobs due to mergers, down sizing, and changing technology. People are unpredictable, they can leave, get sick, and they can die. When they do, so do the plans, dreams and hopes that were connected with their role in your life. You cannot be happy all the time.
Happiness is an experience.
It is a feeling you have when you are doing something you enjoy, spending time with someone you love, or just remembering something from the past. It is a temporary state controlled by your attitude towards the events, the people and things in your life. Happiness is never perfect. I am much happier. Questions about human happiness are not new they have been ask throughout time.
