America's leadership and prestige depend, not merely upon our unmatched material progress, riches and military strength, but on how we use our power in the interests of world peace and human betterment.

Now I think, speaking roughly, by leadership we mean the art of getting someone else to do something that you want done because he wants to do it, not because your position of power can compel him to do it, or your position of authority.

Nobody is going to delegate a lot of power to a secretary that they can't control.

If I am often seen at the theatre, people will cease to notice me.

More glorious to merit a sceptre than to possess one.

Uneasy lies the head that wears a crown.
