I had been looking for this following quote and just found it. It mostly relates to the issue of "avoiding all pain" and whether we should draw a bright line against all high risk / high adrenaline enterprises.
Quote from Plutarch
14. Plutarch, On Peace of Mind, 2 p. 465F (Johannes Stobaeus, Anthology, 29.79): For this reason not even Epicurus believes that men who are eager for honor and glory should lead an inactive life, but that they should fulfill their natures by engaging in politics and entering public life, on the ground that, because of their natural dispositions, they are more likely to be disturbed and harmed by inactivity if they do not obtain what they desire.
