I personally believe that real happiness not the 3 second happiness that fades away, it has anything to do with our possessions, our environment, or even our health; it comes from being happy with your life and expecting who you are and what you have in life.
All in all I feel that there different types of happiness and that some fade away and some stay with you for the rest of your life. People can be happy by the little things in life, while some can think like there never happy, but the truth of the matter is happiness is an emotion that comes from the inside and cannot be taken away.
