Marcus AureliusBe content with what you are, and wish not change; nor dread your last day, nor long for it.

Marcus AureliusIt will suffice thee to remember as concerning pain ... that the mind may, by stopping all manner of commerce and sympathy with the body, still retain its own tranquility.
Marcus Aurelius
