First and I personally think it is the most important quality of a good life is happiness. Nobody tell you to get happy, it is something that you have to require by yourself. When you are happy, you feel like you have the power to do anything, say anything, and go anywhere you want. When you are happy, you see everything positive, then you will be nice to your co-workers or classmates. If you are happy, you will have more friends. The more friends you have, the happier you will be. It is like going in a positive cycle. If you are unhappy all the time and not very cooperative with other people, you will most likely to get no friends. When you don't have friends, you feel sad and feel left out. Now you are going on a negative cycle and it is hard to get out of that. So it is important to start of in a positive attitude.
