Slightly off-topic but in the vain of ancient wisdom, about a year ago I randomly plucked this book off the shelf and bought it: https://www.amazon.com/How-Be-Friend-Ancient-Friendship/dp/0...

There are many sentiments in that book that are highly relatable and one marvels at how long ago they were written. Of course, there's also a fair share of things to recoil from.
