A single lie destroys a whole reputation for integrity.
Nothing arouses ambition so much in the heart as the trumpet-clang of another's fame.
All victories breed, and that over your superior is foolish or fatal.
Know or listen to those who know.
Do pleasant things yourself, but unpleasant things through others.
Take care to make things turn out well. Some people scruple more over pointing things in the right direction than over successfully reaching their goals. The disgrace of failure outweighs the diligence they showed. A winner is never asked for explanations.
