What is happiness?

I searched this on Google and unexpected ran into a really good blog answering the question that many people till these days are still trying to define.
So what is 'happiness'? How do we define 'happiness'? How do we become happy?
To be honest, I still don't really know how to answer these questions since my definition of happiness has changed as I grow older.  The way I view happiness now is different than how I used to do.
So, on the post I read online, it distinguishes between pleasure and 'real' happiness.  It shows that happiness is not pleasure. It is not how much money you make or how big your house is because as human beings, we're really never satisfy with things around us.  We might be comfortable and content with what we have now, but those things sooner or later will become unimportant parts of our lives that we either don't care about anymore, or want something else better to replace it.  I totally agree with the author on this. 
To me, happiness is not definable.  It's a feeling that you can't really describe with words.  You just feel it.
When I see my little cousin speaks in Japanese (he's not Japanese), or when I see my other cousin show me her drawings .. it makes me happy.  I'm happy when I see wonderful things in life like this.  I'm happy when I see spectacular things in life.  I'm happy when I'm amazed by the beauty of nature.
Like when I look up in the sky at night... have you ever done that?  It's the most beautiful thing that nature offers to us.  
In another word, I think happiness is something that can be attained through self-realization of wonderful things around us.  We have to look at the positive side of life in order to be happy. 
It is true that life is not perfect, and often what we desire never really come true.  But on the bright side,  have you ever thought how lucky you are to be able to see many wonderful things in the world.  Have you ever thought how lucky you are to be living and thinking about things?
Thinking .. is a very powerful thing.  Ideas and innovations are wonderful.

I'm still amazed by the Internet even though it's 2010 now and we've had Internet for over a decade.
I still don't know how people came up with the ideas to do that.  And also cellphones? Wireless communications? ... all of those things were created by us ... WE have to the power to do so.

Just by thinking of those things make me happy because I know that I have the ability to do something cool like that.  To be able to create wonderful things in life that might make other happy.  To me, that is true happiness.

The blog I mentioned also talked about resilience, and how that is also a key to happiness. It says that the key to happiness is the ability to stand back up everything you fall down or fail miserably.
It is true. I, personally, went through a lot of ups and downs in life and I really think this is a necessity.
If you do not have the strength to get back, then it is really hard to be happy.  How can you be happy if you're not giving a chance?
The way I think is .. you can fail as many times as you want, but it only take one time attain whatever you want.  So as long as it is not 0%. Keep trying!
That is my philosophy.  Even if it's 0%, I want to think that I can make it possible somehow. 

Life, ... time and happiness don't wait for you. You have to catch it yourself .. don't let it go by :)
