"Make the best use of what is in your power, and take the rest as it happens."

Make The Best Use Of What
Make the best use of what is in your power, and take the rest as it happens.
About this quote
From the opening chapter of the Discourses, where Epictetus establishes the fundamental Stoic framework: distinguish what you can control from what you cannot, then direct all effort toward the former. This principle, taught at his school in Nicopolis around 108 AD, became the bedrock of Stoic practice. Seneca expressed it as accepting fate with equanimity; Marcus Aurelius made it a daily exercise in the Meditations.
