When things you did yesterday still look big to you today, you haven't done much today. There is no substitute for practice. Strong players criticize themselves, not their teammates. Take an interest in your squad and friendships will grow along with the success of the team. It takes five players working together to become successful.
Leadership Never be afraid to take charge.
When a teammate gets down pick them up with some encouragement and get it back on track. At practice be the first one on the court and the last one to leave. Talk on the court, direct traffic, let people know when someone is open or when there is a flaw in the defense. What you see plain as day may be hard for someone else to see. Never take any opponent for granted, respect every ones ability.
