What is the answer for your happiness? Or what answer can work for your love ones or for your gross national product of happiness?

I look for the worst downsides and best upsides first. The rest, just works itself out.

Downsides - Most pet pev is mostly, people don't like their work. Then the ABCs of life. Like new Cancers, heart and lung diseases, stroke, Alzheimer's, diabetes, and suicides have been rising. ..First time in modern history, life expectancy is declining in the U.S.
Notice 70% of world population has only 3% of the world's wealth. That makes a great deal of suffering from these greedy bastards that make up only 1% who own most everything.

Upsides - I have thrived most of my life by solving problems with health and have no regrets . Yet always can improve. Best thing is to change myself first, let assholes be assholes. What works for me is being an optimist, attitude of gratitude and being my own best leader in the world. Controling my own destiny rather slheeping to phony leaders who don't care if you or me live or die. My priority, put my life in order and for my circle of love ones. Love ones have also used this one method and love it. It helps alot in understanding each other.

These are means to an end the way I want to feel like, from top to bottom in order of priorities.
1.Love
2.Health
3.Freedom
4.Security
5.Fun or joy
6.Intimacy
7.Flexible 
8.Passion
9.Successful
10.Self empowerment

Try your own list of priorities in your life. Would be exciting to hear your results.
