(Although figuratively it would also be true in several areas of my life.)
Unfortunately, my son also hit a wall. Quite literally:
As you can see in this crappy cell picture, J got quite the knot from running into the corner of the wall yesterday. He wasn't a fan of the ice, but somehow the 10 or so times I was able to apply it to his head, even at only five seconds each, reduced the swelling. Today he only has a nasty blue bruise.
Apparently the advice to just 'push through when you hit a wall' only applies metaphorically.
