Brevity is the soul of wit.
~William Shakespeare

There seems to be many quotes about leadership in non-fiction. Not so many in fiction.

Uneasy lies the head that wears a crown.
~Shakespeare, Henry IV, Part II

…..in a real revolution the best characters do not come to the front. A violent revolution falls into the hands of narrow-minded fanatics and of tyrannical hypocrites at first. Afterwards comes the turn of all the pretentious intellectual failures of the time. Such are the chiefs and the leaders. You will notice that I have left out the mere rogues. The scrupulous and the just, the noble, humane, and devoted natures; the unselfish and the intelligent may begin a movement - but it passes away from them. They are not the leaders of a revolution. They are its victims: the victims of disgust, of disenchantment - often of remorse. Hopes grotesquely betrayed, ideals caricatured - that is the definition of revolutionary success. There have been in every revolution hearts broken by such successes.
~Joseph Conrad, Under Western Eyes

He was obeyed, yet he inspired neither love nor fear, nor even respect. He inspired uneasiness. That was it! Uneasiness. Not a definite mistrust — just uneasiness — nothing more. You have no idea how effective such a... a... faculty can be.
~Joseph Conrad, Heart of Darkness

To be vested with enormous authority is a fine thing; but to have the on-looking world consent to it is a finer.
~Mark Twain, A Connecticut Yankee in King Arthur's Court, chapter 8 “The Boss”

…………… and to him with loyal awe
The people looked for leadership and law.
Ten thousand knights, the safeguard of the land,
Lay like a single sword within his hand;
A hundred courts, with power of life and death,
Proclaimed decrees justice by his breath;
And all the sacred growths that men had known
Of order and of rule upheld his throne.
~Henry Van Dyke, The Vain King

Freedom is slavery some poets tell us.
Enslave yourself to the right leader’s truth,
Christ’s or Karl Marx’, and it will set you free.
~Robert Frost, How Hard It Is to Keep From Being King When It’s in You and in the Situation.
