Prosperity makes some friends and many enemies.

All men are born truthful and die liars.

When we feel that we lack whatever is needed to secure someone else's esteem, we are very close to hating him

Our opinion of others is not so variable as our opinion of ourselves.

Men are not to be judged by what they do not know, but by what they know, and by the manner in which they know it.

Sometimes a lengthened period of prosperity melts away in a moment; just as the heat of summer flies before a day of tempest.

When an idea is not robust enough to stand expression in simple terms, it is a sign that it should be rejected.
