A prominent college professor announced to his class that they would sit the final exam on their 1st day. The challenge would then be how they could learn together enough material to ensure that when it came to the day they would pass with an A grade.
What this did was first show that people did need to learn, it also gave the students the vision of achieving an A grade. He was showing them what the future was going to be like and stoking their imagination to work hard to achieve success.
At work this is also critical - sit down with your people and ask them what they want to achieve and how you can help them achieve it......give them hope, give them an idea of what success will look like.....motivate them to succeed.
