Optimists tend to interpret their troubles as transient, controllable, and specific to one situation. Pessimists, on the other hand, believe that their troubles last forever, undermine everything they do, and are uncontrollable.

The best leaders don't create followers; they create more leaders.

Fame is vapor; popularity an accident; the only earthly certainty is oblivion.

All mankind... being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.
