There are several autobiographies out there written by great basketball players. These books will teach you the work ethics necessary to become successful. They’re motivational. Reading about someone else succeed and how they did it is a good lesson about how you can succeed.
I remember reading about how Pete Merevich used to bring a basketball with him everywhere he went and so I started bringing a basketball around everywhere I went. I remember reading about Dennis Rodman’s intense workouts, so I started working out longer and harder. Once you learn how the great basketball players because great and how hard they worked then you’ll be more likely to do what they did.
Also at many summer basketball camps I went to they played basketball videos during lunch time so we kept learning 24/7.
