Not comparing to anything but let's say it's a random scenario. You get -blam!-. You say it is what it is and live on? You are wrongfully tried in court. You say it is what it is and live on in jail? You are brutally beaten by police officers and get no justice. You say it is what it is despite you're now crippled and have a mangled body and live on? Not a good philosophy in my opinion. "Live it up, live it right." Try that one.
