Habit - A recurrent, often unconscious pattern of behavior that is acquired through frequent repetition.-- The American Heritage® Dictionary 

Each activity in sports has a correct way to perform and a way that only gets by. Whether throwing a ball, shooting a basket or passing a puck, there are techniques that provide better accuracy, distance and success. Excelling and playing at advanced levels requires the mastery of these better techniques.Replacing old techniques with new ones is not easy. The ability of the human body to walk and move without much thought also makes it difficult to change techniques. 

Many experts estimate that it takes approximately 21 days to break old habits and create new ones. For players, this means that learning new skills may require weeks of consistent thought and effort until these new skills are mastered. Like many things in life, consistency and patience are the keys to success.
