If it is not right do not do it; if it is not true do not say it.

Marcus Aurelius

Effectiveness begins with elimination. Choose your ignorances as carefully as your interests.

The Stoic Emperor

Accept who you are. Unless you're a serial killer.

Ellen DeGeneres

The tranquility that comes when you stop caring what they say. Or think, or do. Only what you do.

Marcus Aurelius

The wise man is neither raised up by prosperity nor cast down by adversity; for always he has striven to rely predominantly on himself, and to derive all joy from himself.

Seneca

He who fears he will suffer, already suffers from his fear.

Michel de Montaigne
