What you are capable of achieving is determined by your talent and ability. What you attempt to do is determined by your motivation. How well you do something is determined by your attitude.
You've got to have great athletes to win, I don't care who the coach is. You can't win without good athletes but you can lose with them. This is where coaching makes the difference.
All winning teams are goal-oriented. Teams like these win consistently because everyone connected with them concentrates on specific objectives. They go about their business with blinders on; nothing will distract them from achieving their aims.
