As teammates, it is imperative that we let our fellow teammates know how important their abilities and contributions are, and then we can hold each other accountable for them. As coaches, it is important to let your players know their importance in the success of the team and why, instead of only correcting them and emphasizing their weaknesses. If players know you believe in them, it is easier to then hold them accountable and expect them to meet high standards. Your belief allows you to push them harder, and have them respond positively. Your belief makes them tougher.
