Borrowing a few lines form HIMYM;

Ted: Kids, your grandma always used to say to me, "Nothing good happens after 2:00 a.m.," and she was right. When 2:00 a.m. rolls around, just go home and go to sleep because the decisions you make after 2:00 a.m. are the wrong decisions.
As one belonging to the "been there, done that" generation, there's some truth to that advice.
