Truer Words Were Never Printed on an Image of a Bust of Plato

Platoquote
Sometimes, man...sometimes, you come across some wisdom, and you're like, "Damn! That's some serious wisdom! I'd better slap those words on an image of the person who said them and put it on the Internets, like, stat!" (I assume that you are a retarded medical doctor in this hypothetical situation.)

Anyway, since I am incapable of coming up with wise words of my own, obviously, I present these words to you, spoken ages ago by an old Greek guy. Let them guide you in times of darkness, like a bottle of magical Elvish sunshine.
