The term 'lazy' here is a bit misleading. In my view it's not meant in the sense of someone who slothful, but rather someone who aims to do things as efficiently as possible. Sticking with the military context, one of the British Army's principles of war is 'economy of effort', which I think is a better description. Effective leaders focus on the high value activities, use resources well and delegate.
