You can't motivate a group of people or a Team. You have to motivate people individually, and that motivation has to be in an environment in which that person has a goal - something they want to accomplish in their lives.
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.

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.
Teamwork is the foundation of success. The three universal questions that an individual asks of his coach, player, employee, employer are: Can I trust you? Are you committed to excellence? And, do you care about me?
