The heaven of the envied is hell for the envious. [...because they focus on what they don't have rather than being grateful for what they have, which is always better than some others.]

The passions are the humors of the mind, and the least excess sickens our judgment. If the disease spreads to the mouth, your reputation will be in danger.

Know how to ask. There is nothing more difficult for some people, nor for others, easier.

The envious die not once, but as oft as the envied win applause.

Superiority is always detested.

Nature scarcely ever gives us the very best; for that we must have recourse to art.

Excellence resides in quality, not in quantity. The best is always few and rare; much lowers value.
