Happiness...first i think that happiness can be a word with different meanings, it depends the person,well many people have a different concept of happiness, is a wonderful emotion i think that happiness is when you have a great, a satisfied mood and i think that is important that you know that happiness dont depend of material things, happiness is not material things..is a feeling and if you want to be happiness i think its outstanding that you know.
We know that happiness its a feeling but also more feelings are involved and also wishes, most of us have wishes, want things, want success but also this can be bad because you would be ambicious,you want more and more and then you maybe dont know that you are ambicious.
For many people happiness depends of money or properties like hauses or cars material things make your happiness and maybe you can hvae pleassure about your properties or money but you happiness is not secure, you would have all the money all the material things but maybe you are not happy,a clear example is the famous people that they have lots of money but their alone or have problems and waste all their money and finally they end with anything, maybe the elderly is sad because many of elderly ends in a (acilo) a special place for only elderly people and they end alone and their families forget them.
Well for finish this, i conclude that happiness is 99% based on feelings in love, affection,satisfied,success and other things make you happiness,feel is outstanding and also the affect and relation that you have with the other people who you appreciate and love is important.I recommend you to see the movie "Pirsuit of happiness".
