At the risk of sounding arrogant, I will out myself as being incredibly smart and also incredibly unhappy in a general sense (although content with my life). The answer is very simple and mundane: I observe and understand problems that have simple solutions that will never be applied because the mass of people cannot understand the problem and solution or are unwilling for social reasons from implementing the solution. This creates a sense of powerlessness and futility, and if you aren't careful can cause you to spiral into nihilism. Finding stoic philosophy was a major turning point in my life, because it helped me gain the perspective to understand that I should invest my mental efforts on things that are within my control. That's helped me be happier in my 40s than I was in my 20s.
