Particulary, this section was interesting:
"According to Epicurus, a pleasant life can be achieved with the absence of pain and fear and by leading a self-sufficient life surrounded by friends. He also said that pleasure and pain are the measure by which we should decide what to prefer and what to avoid. Pleasure is morally acceptable and should be pursued, as long as it ensures that we obtain inner peace. If this is achieved through pain as well, then pain also becomes a positive force. Therefore, choosing among pleasures is no longer a matter of quantity, but quality."
