Teams do not go physically flat, they go mentally stale.
Winning is not a sometime thing; it's an all the time thing.
You defeat defeatism with confidence.
You carry on no matter what are the obstacles. You simply refuse to give up - and, when the going gets tough, you get tougher. And, you win.
Inches make champions.
Don't succumb to excuses. Go back to the job of making the corrections and forming the habits that will make your goal possible.
