The meaning of happy for me

Happy is a simple word and it's easy to be happy, right? I'm not entirely sure whether you mean this or something else.
Money doesn't necessarily make you happy but if you have a money you can make people around you happy too. :)
I am happy when i can make people around me happy too and also when I always see my family happy . I have changed the "too" in the second sentence to "also" as we generally avoid using it twice in one sentence.  It wouldn't be wrong to use it twice but it sounds nicer if you don't.
And i have mood booster; his name Dian. He can always make me smile, is always patient with me, always gives me support when i feel so weak.
So, what is the meaning of happy for you ? ;)
