Letters 71.3

The archer must know what he is seeking to hit; then he must aim and control the weapon by his skill. Our plans miscarry because they have no aim. When a man does not know what harbour he is making for, no wind is the right wind. Chance must necessarily have great influence over our lives, because we live by chance.

Seneca, Letters to Lucilius 71.3, translated by Richard Mott Gummere
