Reality

We might not like to see it, to some its the one thing they would love to see and at the same time love to never see again. We have split emotions about it, sometimes its better to ignore it, other times one needs to take a long hard look at it. Reality is different from person to person, some let it pass by and some of us analyze, dissect and try to put it in system.
One thing stays a constant regardless of what you do, Occam's Razor. It's a fun principle and goes nicely in hand with When you remove the impossible, whatever remains, however improbable, must be the truth" from Sherlock Holmes. If you first apply Occam's Razor to a problem, and then Holmesian deduction most questions and problems will be solved or at the very least understood better.
However once you add Illusory superiority into the mix we lack the needed objectivity in most cases to judge ourselves. People tend to come in 2 categories, the ones who judge themselves too lightly and the ones who do it too harshly. Very few people if any of the ones I've met tend to be on the mark with every aspect of themselves.
