We have been made to think certain things are absolute truths for most of our lives.  Take, for example, the saying that practice makes perfect.  While this sounds great in theory and can be a great motivation to pursue growth opportunities, an underlying fallacy is embedded in this message.  Take bowling, for example.  The ultimate goal of any bowler is to reach a perfect score of 300 by getting nothing but strikes.  By any standards, this is an impressive feat.  While perfection can be achieved with the right amount of practice, you would be hard pressed to find any professional bowler who scores a 300 consistently.  Hence the need to constantly practice improving performance.
