No matter how far you’ve fallen back, you still have to stand up and resume. Simply staying down won’t bring you anything.
You may have been pushed back by a hundred steps. That happens. All you can do is shake off the bitterness of the loss and move forward again. Yes, you’ve already been there - those hundred steps ahead. But now you’re here, and you have to walk those hundred steps again.
Because with every single step, you’re getting closer to your goals.
There is simply no other way around it.
