As a serious basketball player, student, or in a professional career you should always evaluate and reflect on your performance with an improvement mindset. You must be objective and specific as you look to identify areas that will propel you to the next level.
Accurate evaluation is one of the most difficult things to come by. However if you know how to seek out genuine constructive criticism and are able to accept it, this will put you far ahead of the competition on the court and in life.
