Happiness,

I am using quite much Orkut and there is tradition that every day you get a new fortune sentence. So I did got it also today, and that made me to think about it. The sentence I got is:

Today's fortune: Get happiness out of your work or you may never know what happiness is.

This sentence made me to think, what is happiness at all? Is it something we can see or feel or hear? Does it has colors or looks? One question just raises other one and so on and on. What would people see or think about happiness?
I believe as many people lives in world, as much different opinions,feelings they think about, when you ask from them, what is happiness in their opinion.
So that means, I can say only my own opinion about it and see, how others think about it, if they happens to read my thoughts and opinion.
For me, I can see that happiness is something what makes me smile, makes me to think back for good times I have had and think about future for times to come. I believe, that even on a hard rough day, you can find some strength inside what makes you smile and happy. I believe that it is something what makes me feel good. So in my opinion I can say that it is the way I feel and my mind is. You can be happy over small things and over big things, sometimes I think that a small thing can overweight bigger things and just a small thing can be beginning for something bigger and it gives end result, that you are happy and joyful and feeling well.

I also looked up at Wikipedia what they say about happiness and there was quite many things. So I decided to add link here, that you all can see and read about it self :)
