Colonel Chris P. Levy shares that a good leader is like the fireman on a steam locomotive. If the team needs to work harder due to an impending challenge, the leader can pour on the coal to increase output. Once the challenge is overcome, the leader can reduce the fire to give the team a much-needed break. The key is finding that balance between the two extremes. Determining the appropriate balance to obtain the maximum performance from your team while keeping them motivated, energized and ready for the next challenge is the key to excellent leadership.
