fact is we re programmed to have a family, a socio professionnal occupation that pays enough for us to buy a car, a house, a pool, some vacations here and there, we re programmed to have sex, to eat, shit, reproduce and select then teach the best of what we ve learnt to our offspring. As long as you can do all of this with people who care about you as much as you care about their own well being, you have the key to "hapiness" or, the reciepe for producing the good chemistry of the diff fluids/neurotransmitters in your brain.
This is why you have people who achieved a ton of things and are unhappy (often the ones who have no family), and you have people who achieved the minimum and are happy as pigs in their shit. Meaningful deep relationships with only a very few loved ones -you cannot develop deep relaitonships in a lifetime with more than two or three persons, we re simply not designed for that- are fundamental, even if you dont have money, social status etc cause they keep making you feel better until you reach these goals.
Hapiness and intelligence are two very different things.
Animals and humans solely exist for the only purpose to ...exist. This is life. They fight, survive, adapt, reproduce until they die. Humans just developped more complicated strategies of survival but everything we (nature, evolution, natural selection) developped is in itself a strategy of survival. Everything that you think about or do is about making yourself feel better in a close or projected future. This is the way our brain works. It's purpose.
People who arent loved want to destroy, kill, harm, torture others. People who ve been loved just want to love and be loved. A never ending circle.
This love thing has to follow some principles to be truly effective tho. Loyalty between parents is the key to raise offsprings who will feel loved and will love, and contribute to society in return. Two parents who dont love each others enough to live together cannot teach love to their offpsrings.
Money doesnt make you happy, it helps, if you ve been loved and are able to love and if you have a resilient and positive entourage of family members or friends. You can give as much money as you want to someone who havent been loved -by a father, mother- he ll be unhappy all life long and will try to compensate for this lack of initial love by sinking into various addictions, these addictions depending of your place in the social ladder -riches will party with strangers pretending to be their friends, will consume expensive drugs will seek for attention doing extravagant shit while poor people will torture their children, fight each others for nothing , eat or drink too much etc-.
We have unlimited possibilities -but not unlimited capacities as some can do things others cant- but not unlimited ressources, as we age we lose energy and tend to understand the concept of economy ... You could potentially fuck every woman in sight, but you couldnt give a proper education -an education that makes children then adults happy- to all of the offsprings , or maybe in a polygamist way of life where all women and kids are raised in the same place.
