    How good are you with money? What about reading people’s emotions? How healthy are you, compared to other people you know? Knowing how our skills stack up against others is useful in many ways. But psychological research suggests that we’re not very good at evaluating ourselves accurately. In fact, we frequently overestimate our own abilities. David Dunning describes the Dunning-Kruger effect.

      I actually don't fit into the dunning-kruger affect. This is because my moral code halts me from believing I'm better than I actually am, which is hard, which is why I constantly underestimate myself in preparation. Sadly though, I actually participate way better than I could ever expect(according to other people) which leaves blankness in place of pride, which is also my goal(to not be prideful).

      The thing is though, competency comes from common sense rather than intelligence. You can have a 200 IQ, but still be incompetent if you don't have those street smarts.

              I'm not really a smart guy. But my friends and family think I am. I mean, I'm not at the top of the class, and yes I make thousands of mistakes. Plus I'm really terrible at math, I just grind my brain off to learn the topic. This situation bothers me because one day I might be convinced that I really am smart and look down on others. Arrogance is one of the things I hate the most and I surely don't wanna develope one. But in my opinion, I think respecting the abilities of others but not putting yourself completely down is the answer to "just enough self-esteem."

                    By overestimating ourselves and ultimately failing, we can determine our limits. From an evolutionary standpoint it may be a beneficial trait.

                                              Sometimes I let other people do parts of important work just because they look so confident (at least more confident than me) like they know what they are doing and they end up blowing it up because of poor decisions (that I would have never made because I am aware of my inexperience so I wouldn't rush it) and lack of experience. Fun part is they are always the ones who voulonteer to do the job (like its peace of cake for them) xD

                                                        Not surprising when one considers how, since WWII, most people's upbringing, and even more, their school experiences, have emphasized "self-esteem" and "feeling good about oneself" far more than actual competence and learning, still less critical thinking skills. The only results possible will be those showing large numbers of high school, even college, graduates, who can barely read and write, and Presidential candidates who can barely speak in complete sentences.


                                                        Any surprises here? Emphasizing "social skills" and "feeling good about oneself" over competence, intelligence, and actual real-world problem solving will (especially for children and adolescents who are already somewhat mentally challenged) fill the world with fools!

Does that mean you're overvaluing, undervaluing or are being realistic with your assumed ability? Generally, I think I'm below average in most areas so just curious. Maybe it's the same problem in reverse, where you can't see what you're doing well.
