OK wise guy, define happiness?

Since I've been blogging a lot about happiness, a friend asked me to define it? That sounds simple enough, right?
Not so my friends. Forget the dictionary it gives you only a superficial answers such as delighted or pleased. And don't bother with the so called great philosophers because they will take up a 700 page book to get to some vague answer. They will break it down as lasting happiness or fleeting, natural or chemically induced and so forth. Fear not my friends, I just spent the past two weeks reading everything I could find and I have reached a conclusion!
Here is my definition of 'true happiness' (forget the superficial momentary stuff). True happiness is the ability to radiate positive energy regardless of external or internal circumstances.
This is not to ignore fear, sorrow or anger but to have the ability to feel those emotions and after a period of time to come back to happiness because that's what you decided you want. So then it follows that not many of us have mastered true happiness. Put your guilt aside and its quite possible to watch the nightly news and see and hear stories of murder and starvation feeling sorrow and even anger, while underneath the happiness remains waiting for you to decide to bring it to the surface.
How much happiness we experience has a whole lot to do with where we put our focus. It's obvious that if we focus most of our attention on things that don't make us feel good we aren't going to be happy very much. So being happy has a whole lot to do with controlling your thoughts, think positive happy thoughts and that's the way you will feel.
I just got a great idea! Think of a moment when you experienced 'perfect happiness'. Record that moment and any others you can think of, so that you may re-visit it any time you wish. Those magic moments are precious. Sometimes they might be hilarous moments and other times it might be a time when you felt connected with nature or god, you decide. Then whenever you feet a little unhappy you could easily recall the good stuff and instantly change the way you feel. An instant mood changer (sounds like an infomercial).
One more thought, crap happens in this world that is out of your control. Try to remember this; it is very difficult to change the world. It is however, easier and a lot more fun to change the way you look at it.
Happiness is the most contagious energy on the planet. The more we bring into the world the better it is for everyone. Nothing can bring us nor do we really want to be in a state of pernament happiness. Happiness is a moment to moment thing that with practice is accessible on demand.
I'll leave you with two thoughts...

Happiness doesn't come from getting what you want
it comes from wanting what you get

Don't sweat the small stuff
because its all small stuff
