How can you achieve life-long happiness?

Happiness is something that everyone try to achieve in their entire life. Some people may think that be a rich people will be the happiness, some may think that being sucess is the meaning of happiness. Happiness can be easily be achieve by many ways. For me, money and sucess is not happiness but it just something that we force to have so that we can pay our house's rent and car. Since we force to do something, why is it happy? In my point of view, i think that happiness can be easily achives base on what you think and are you willing to be happy. I used to be unhappy last few years and i used to think that i will not be happy in the future. Until one day when someone made me feels that happiness can be everywhere and everyone deserve to be happy after they born in this beautiful earth. I believed the words and feelings and i become happy everyday now. hehe: D Hope everyone happy for their life.
