"So often what people say their problem is, really isn't their problem. Their problem is their attitude which causes them to handle life's obstacles." John Maxwell
One of the most essential characteristics of a leader is optimism.
The leader has to believe with all their heart that the mission is going to be achieved. If there is any inkling of negativity, every person that follows them becomes a passenger on a trip to nowhere.
Research has shown that optimism is a competitive advantage. In a study conducted at Duke University by Manju Puri and David Robinson, they found that optimistic people work harder, are paid more, win at sports more often, are much more successful in getting elected to office, and live longer.
In the book by Walter Isaacson, Steve Jobs , the author talked about Job's Reality Distortion Field . He was continually inspiring his team to push further, to achieve almost impossible things and meeting ridiculous deadlines regularly.
What Jobs did was lead his team out of thinking pessimistically, or in many cases realistically, into overbearing optimism. Because of his belief, he created one of the most successful company's ever and changed the world.
To achieve the unthinkable, you can't think like everyone else. You have to believe without a shadow of a doubt, you can accomplish it. If everyone thinks you're crazy, you're probably on the right track.
