What Is A Well-known Short Quote

What is a well-known short quote?

Keep going even if you’re going through hell. There are a terrible lot of lies out there, and the worst part is that half of them are actually true. The price of greatness is responsibility. Realizing that even fools can be right occasionally is life’s greatest lesson. There are only two tragedies in life: not getting what one wants and getting it. The truth is never simple or pure. The only sin is stupidity, not anything else. Not being talked about is the only thing in life that is worse than being talked about.
