I've always found this quote by John Paul Jones to be the best guide of leadership (and behaviour):
``It is by no means enough that an officer be capable...He should be a gentleman of liberal education, refined manners, punctilious courtesy, and the nicest sense of personal honor... No meritorious act of a subordinate should escape his attention, even if the reward be only one word of approval. Conversely, he should not be blind to a single fault in any subordinate.''
--- John Paul Jones (Scottish born American Naval Hero in the U.S. War of Independence, 1747-1792)
