Happiness is the one of the wonderful key to living life. And this word is totally depends on your mood. When you think about any special thing in your life, and by occasion you get the same. This one is the happiness.
Although not everyone agrees on how to define happiness, our experience speaks for itself. There may not be one simple happiness definition, but research may well point to one that describes more satisfied people. Happiness can be defined as freedom from unhappiness, continued sadness, remorse or regret.
Happiness and unhappiness are opposite sides of a judgement about your situation. If you judge your situation as bad for you, that's unhappiness. If you judge a situation as good for you, that's happiness.
According to me, happiness is the moment when you get the satisfaction of your face and smile and the people you make them happy ........, unit measure.happiness is not feeling you get when you totally love And accept yourself for who you are. All restrictions on the freedom of life and just feel the benefits.
