my moment

Every time I want to start over and move on, this question just pumps up in my head. What is happiness?What ingredients do I need to feel it? How long doest it last?I move around the world and see things, meet people and live a life. But even having this I dont feel content. It does bother me a lot. Today I was on a bike to 7-11 and I caught myself having this feeling-the moment of happiness. My moment is when I feel like everything is possible..my dreams in my head and my plans for the future. The sun always shines. At this moment I feel happy...like really really happy..emotions flood! This moment is always short. It lasts about the time I get to the location I go by bike. It is said that there is a hormone that controls the level of happiness. Someone said that chocolate creates endorphin that can make u feel better. But too much chocolate leads to an allergy. So may be too much happiness is bad for us as well....or should I drive bike all the time?!)
