I think the happiness, more than a emotional o mental state, its a way to life, i knows that sounds "cliché" but I find some reason in that sentence. 

Finally, oneself is makes the day or the whole life wonderful and happiness. 

There are many things that makes people happy, one of this it could be the family, the family is always a good reason to smile. 

Do things that you like and enjoy like dance, sing or any thing you take pleasure in, they make you feel hapy. 

But today, in this society, money sometimes buy happiness (but i dont think so) 

I happy when y travel to Punta Arenas and meet with my family, for me, is the best thing in the world. But dance, take pictures, eat, sleep, wake all days are other things to makes me happy. But as I say before, happiness is a way of life, then ,althoug some thing  contribute to my happiness, im happy. :) 

I show my happiness of the many forms: I always smile to the other people, and I laugh a lot. I dance too much and singing aloud. 

I think that i do little things for others smile and be happy for a moment, like a smile, a hug, a greeting, make gifts or say us something positive.
