In this quote, the speaker reflects on the feelings of envy that may arise from youth. He suggests that as an older person, it is unnecessary to dwell on missing out on the vitality and strength of youth, as doing so can be self-punishing and unproductive.
"There are times when your youth envy you, but I try not to think much about that. An old man should not be jealous of those who come to occupy his position, and remember the time when he was young, healthy and virile is an act of masochism that is useless."
