Intelligence without ambition is a bird without wings.
-- C. Archie Danielson
Honest men esteem and value nothing so much in this world as a real friend. Such a one is as it were another self, to whom we impart our most secret thoughts, who partakes of our joy, and comforts us in our affliction; add to this, that his company is an everlasting pleasure to us.
A leader knows what's best to do; a manager knows merely how best to do it.
