The Wall - Free For Commercial Use - FFCU
The wall is nothing but a solid structure designed to hold and support.
Do not hit a wall because it will hurt. Instead, climb over the wall, walk around the wall or use the wall to support you.
"I've hit a brick wall" is a saying used by those that cannot see the bright future that lays ahead of them. So think before you 'hit a brick wall', it will hurt less. :)
