It is very easy for a leader to be passionate about accomplishing the mission they have set for the team. The difficulty, however, lies in infecting the members of the team with the same passion. The leader can not just issue an order that henceforth every member shall be so passionate. The only way open for the leader is to make them see clearly what is there for each of them in the success of the mission and make them like it, rather desire it and crave it. Then, and only then, the entire team will join the leader in the enterprise and make an unqualified success of it.
It is a very tall order but not for the leaders who are thinker-visualizer-doers, who set examples for others by their conduct, who live the welfare of their people and who communicate from the honest depths of their hearts.
