How to be better at basketball : Mental Conditioning

Knowing your Basketball Philosophy 

Before ever playing it is important to set a basketball philosophy that the team can look to and will follow throughout the season . In the book " How to be better at Basketball "it says " every basketball team in the world is led by a philosophy that reflects core ideas that lay at the heart of its foundation. This philosophy guides your decision making as a team ( Wilson, James Basketball ) ". The Kentridge Basketball program includes a packet for all the players before the playing season begins " The plan of a champion ". It includes : Athletic Attitude , Roles of the Coach, Player and Parent. The team commandments and life lessons for players , and in the back the most important section " My Plan of a Champion ". This plan helps me create a motto and goals to set , and a philosophy to follow throughout the season. With this it will help me have a better mindset and dedication while playing basketball.
