Happiness is used in the context of mental, emotional states including positive or pleasant emotions.
Happiness is the subject of the debates on uses and meaning, and on possible difference in understanding by cultural.
I personally believe that is important for each of us to give back to the community.
You have the power to be happy. You can do anything fun that you enjoy.
If situations come up where there is some good and bad look at the good things and left the bad slide. Remember the good part so when you look back you do not receive bad memories.
All human beings need to realise the importance of happiness in life and discover what personally fulfils their happiness so they can live their life being happy or every should.
