“No wind is favorable to the sailor who does not know to which port he is sailing.”Seneca · Scrisori către Luciliu · 65 · Scrisoarea 71
The wind doesn't choose the course: only those with a port can be carried by luck.
Seneca is talking about direction, not luck. A good wind helps only someone who knows where they want to arrive; for anyone else, the same wind is just noise. Opportunities appear constantly: an acquaintance, a course, a job change. They become favorable only when a port exists, meaning a defined goal. Whoever cannot name it keeps waiting for perfect conditions and misses them all, however friendly they are.
Why it matters It serves anyone waiting for the right break before deciding what they actually want from work or life.
