A Weekend of Rest
The result is a few days of bedrest and doing absolutely nothing. It's not my favorite thing in the world to do, but it's the solution to complete exhaustion and the need to recuperate.
And I will come upon him while he is weary and weak handed, and will make him afraid... 2 Samuel 17:2
Instead of getting to the point where you have no choice but to collapse, make this a weekend of rest. Even if it's just for a few minutes, completely relax and rejuvenate. If we get too worn down, we'll have a harder time fighting when it's necessary.
So grab a cup of cider, find a good book, put in a movie or just close your eyes. Take a few minutes, a couple of hours of the better part of a day and recharge your batteries. Your body and mind will thank you.
