A shattered mirror produces a thousand tiny daggers. Mirrors show us exact reflections. We get an accurate measure of how we physically appear to others. Looking inside, however, is not so easy. It requires time, reflection and honesty. Without these we form assumptions and are unable to evaluate ourselves accurately. Sometimes we are asked to evaluate from external sources and sometimes from internal sources. Whatever the cause, it is a necessary step for our improvement. For many, the seven years of bad luck that comes with breaking a mirror would be much preferred to honestly looking at one's reflection. We can feel comfortable with a little bad luck while having the crutch that “we're doing okay.” Alternatively, self-assessment can be difficult. We often believe we have little to improve, but more commonly we believe we can make improvements but have no concrete goals or characteristics to improve. We will explore some tools that will present us with solutions to this conundrum. We often look at ourselves through our built-in psychological mirror and lie. An honest self-evaluation may hurt, but in this game there is no gain without pain. Beliefs and facts are often victims of convenient substitution. We like to label our beliefs as facts when they fit our wants or needs. Our internal dialogue is a strange juxtaposition of persuasiveness and gullibility, and we often fall prey to the effects of this dynamic. I once had a friend who constantly complained that no one was as optimistic as him. Without true self-evaluation, we will only sink deeper into the comfortable quicksand of our illusions. Sometimes we are forced to evaluate through the feedback of others, other times through our own observation. The evaluation made by the interaction with the central part of the sheet, according to which each step is separate and builds on the others, shows us a further point to consider: the details. Da Vinci and Einstein did not become renowned for their disregard for detail. Without embracing the details, they would not have had the progress they have had. When proving a theory, if a scientist finds that his hypothesis fails once, he must abandon it and devise a new plan. Our development depends on our attention to detail. If we find that our recipe for success fails in a certain set of circumstances, we need to go back to our evaluation and find the detail we missed. This is a never-ending process that will produce continuous results with continuous effort. Take a look at the internal mirror and observe. Leave your assumptions somewhere you can't get to. Be honest with yourself. The fastest way to fail is to reject reality. Find reality, accept it and change it.
