You don ' t need another human to make you happyI think you ' re projecting your introvertedness a bit , my dear . Extroverts , by definition , need people around them to be healthy and happy . It ' s a fact of our existence . <| sep |> There aren ' t that many . Yes a college degree isn ' t a guarantee of success or great accomplishments and unfortunately not even of proper education . Yes some people who never went to college , or more commonly that left before getting a degree and went on to achieve great success exist but are one in many , many individuals . For most of the population the fact that you have a college degree in a proper subject and from a good college grants you a proof that you are knowledgeable in , usually , advanced subjects and that ' s provided by the reputation and the forced evaluation to it ' s students , that the same degree diploma certifies , ensures that you learnt it properly , something that many selftaught people lack that is sometimes very wrongly overlooked by people that never attended . This is more to do with being educated or otherwise and not smartness in itself though whether or not smartness or inteligente increases when you put yourself through learning things like engineering and other sciences is another point , which i firmly support btw . A lot of the times what you get out of college is not so much what you learn in the curriculum which is also important ofc but learning to learn and think . Critical thinking develops dramatically and correctly with a good college course .
