Seneca

Lucius Annaeus Seneca was a Roman statesman, dramatist, and Stoic philosopher who served as tutor and later advisor to Emperor Nero. His philosophical writings — letters, essays, and dialogues — are among the most elegant treatments of Stoic ethics in any language. Seneca was preoccupied above all with the right use of time: how to live fully in the face of mortality, how to resist fortune's reversals, and how to cultivate the inner freedom that no external circumstance can touch.
