From Aristotle's last letter we can all draw lessons for ourselves and for ourselves. We will not talk about his last letter at length. We will only mention the sentences that may be necessary for us as the last lesson. If you are ready, let's begin.

"Even if you throw a stone ten thousand times, you cannot teach it to fly."

"Spend your energy on the right things and the right people."

"A stone is not a bird and a bird is not a stone."

Take the lesson you need. Which one is your favourite?
