There is power in silence.
Some people make their message heard by a loud voice while others say the loudest thing in complete silence.
A true leader has confidence in what he can do and does not doubt his ability to lead even without raising his voice. He leads by action and not by meaningless words.
A true leader does not boast his achievements, he shares them with his people instead, making sure they also succeed in what they do. Since it becomes a collective team effort, the chance of success is higher and more often than not, the team actually achieves its goals. When this happens, a true leader does not take credit but commends his subordinates for a job well done.
That is why a person who leads by example and confident in his ability to do so without making noise about it makes the best leader and creates the best team—a sure-fire formula for success.
