The meaning of life is happiness. People’s first instinct is to do what things that give their brain the chemical reaction of happiness, joy, love, or elation. For some people it is playing a sport or a game, others it is painting or seeing the joy in another person’s eyes. In order to fulfill one’s life, they must do the things that make them happy, if money makes someone happy, they make money. If children make someone happy, they have children or adopt. People’s decisions throughout their lives are all based on their happiness.
