I am actually speaking of two walls. The first is a little bit of my own focus. I have not been being as attentive and determined as I previously was when practicing MTM.
The second is a range and endurance wall. It gets much better for a week, then much worse for two, then better again, then worse. Neither the ups nor the downs have improved as much as I would like.
I often make posts for a bit of inspiration to set me on the right mindset again.
