Happiness is a byproduct. You cannot pursue it by itself. You were built to conquer your environment, solve problems, and contribute to society. You'll find no real satisfaction or happiness in life without obstacles to conquer and goals to achieve and purposes to give to.
Happiness is in the activity of giving. It's a running river, not a stagnant pond. Happiness is not in having, it's in doing something you love and giving to something you are passionate about.
