Timothy Zahn said this quote

A great tactician creates plans. A good tactician recognizes the soundness of a plan presented on him. A fair tactician must see the plan succeed before offering approval.Those with no tactical ability at all may never understand or accept it. Nor will such people understand or accept the tactician. To those without that ability, those who posses it are a mystery.And when a mind is too deficient in understanding, the resulting gap is often filled with with resentment.
