You vs. Wall = You Win.
There's a tired metaphor that we almost started this article with:
"Life is a series of challenges, we all have our walls to get over... "
blah, blah, blah - duh!
You're here because you're not the type of individual to be penned in by 4 walls, a cubicle or stopped by anyone telling you that you can't do something. Instead, you search for obstacles just so you can conquer them: ropes, cargo nets, bars, mud pits... and of course, walls!
