The work and contributing continuously is the essence of leadership.
Self interest is never a matter of concern for the leader. He keeps on doing. He is always deeply involved in his work. Work is worship in true sense found in him.
Love your work and work with love, money is only a by-product. He never expects return or benefit out of it. He just does his work passionately and performs because he likes it doing and the work is productive and society is largely benefitted. He is a contributor in the organisation or society, irrespective of what he gets out of it. Even, he hardly thinks about it.
Peace, joy, satisfaction, sound health and peaceful mind are his fruitful returns. In fact, these all are by-products of the karma (action). He lives life full of joy and peace.
Sometimes, you find people who work for self interest and personal gain only, however such people are not influenced by self concern people. They hardly deviate from their path and get disturbed by their motives. They pursue themselves until the things get happened.
Such people works up to the final point and results are benefited by the society at large and humanity is delighted.
LEADERSHIP IS DETACHMENT FROM THE SOCIETY AND ATTACHMENT TO THE SOCIETY
