Thank you cuz i was wondering the exact same thing lol

** edit **

Ok I went diving. Looks like someone just meme'd these in r/wiseposting like a year ago, which itself was inspired by a similar series of memes but about the 7 deadly sins + some others. They have much longer last panels. They're just sort of general philosophical points about the sins/virtues that people have come up with but in meme form it seems.

Temperance = you will live a middle life, buried in a middle grave.

Patience = tides will rise regardless, fight or be swept away.

Humility = know your worth, lest others set it for you.

Charity = true gifts are free from expectation.

Diligence = work is sacrifice, today is for more than tomorrow's gain.

Chastity = joy shared is joy multiplied, it's lack does not create value

Kindness = you will burn from both ends until naught is left but memory
