First of all, we were never individuals. Each of us contains multitudes, different parts with different goals. More importantly, we are profoundly influenced by our social environment. Family, friends, and colleagues; organizations, media, and ideas. The very concepts we use to think are social. Additionally, it is not humans vs. nature, we are nature from the food we eat to the air we breathe - our separation is an illusion. If you ask yourself what makes you happy and inquire there, you will notice that happiness always appears in relationships. Whether you are after power, fame, or good-looking mates - these concepts only make sense in relationship to others. Not to mention that any of these goals are downstream of clean air to breathe. Not only can you not make yourself happy, you don’t even exist as an independent agent.
