No Envy

One way to avoid envy is to do better than the cases you observe.

From this, you will not want the smallest part of another's life. You won't want their wives, girlfriends, material joys, nor any part in their pedestrian food, entertainment, or travel choices.

You would not exchange anything for their outcomes because your choices are better suited for you.

Neither need you say a word against what they pick or advocate for them to make better choices -- they seem perfectly content, and there is no reason to unsettle them.
