Unfortunately, I believe that happiness escapes mostly because they misunderstand the process and journey of finding it. I have heard many people say that, “I’ll be happy when I get my new promotion.” or “I’ll be happy when I earn that extra 20 pounds.” The list goes on and on. You probably have a few of your own you could add if you want.

This thinking is dangerous because it presupposes that happiness is a “response” to having, being or doing something. In life, we all experience stimulus and response. Stimulus is when a dog barks at you and bares his teeth. Response is when your heart beats faster, your palms get sweaty and you prepare to run. Today, some people think that an expensive car is a stimulus. Happiness is a response. A great paying job is a stimulus. Happiness is a response. A loving relationship is a stimulus. Happiness is a response. This belief leaves us thinking and feeling: “I’ll be happy when…”

It has been my finding that actually the opposite is true. I believe that happiness is a stimulus and response is what life brings to those who are truly happy. When we are happy, we tend to have more success in our work. When we are happy, people want to be around us and enjoy loving relationships. When we are happy, we more naturally take better care of our bodies and enjoy good health. Happiness is NOT a response — rather, it is a stimulus.

Happiness is a conscious choice we make every day of our lives. For unknown reason to me, many choose to be painful, unsuccessful and angry most of the time. Happiness is not something that happens to us after we get something we want — we usually get things we want AFTER we choose to be happy.

I have made only one simple rule for my own happiness: Every day above ground is a GOOD day. Therefore, I tend to have a lot of good (and happy) days continually.
