Clarity
It's funny what a little sleep can do to a mind. It comes to you, as soon you are rested and calm: clarity. When you abandon what you cannot get and treat hobbies as hobbies but little else.
Clarity comes making all things easy again. What you believed impossible only needed a little stop and some thinking. Memory works like a champ, the brain is powerful again, hope gets a workout, and you are back in flow.
Rest a little, then meditate, find what's holding you down, and fly again.
Note: It doesn't work all the time, but it pays to try. So try a bit of resting.
