What's your understanding of happiness?

Happiness is a feeling,there are something or someone let you feel happy.For example, my good friend is care of me all the time, she encourage me when I meet some difficulty, she remembers my birthday every year and give me presents every time....I am so happy that I have this so good friend. I'm happiness! The others,my family care of me, I have a good family....this so so let me feel happiness.

(above for u ref, my english is not good,so couldn't express any other things)

My happiness is very simple, and my wife live with their families and friends, so I like to do the work.
