I think, fundamentally, all walls are artificial ones. Any wall
   can be knocked down or bypassed, or gone through. But sometimes
   you may have to change the questions you ask, to get the answers
   you need. I think we often put up our own barriers to success -
   our own "I can't because..." I challenge them when I find myself
   thinking them. I go, internally, "Ok, WHO SAID, I can't?" and I
   try to think it through. Was it a teacher in the 3rd grade? Was
   it a mean fair-weather friend in the 5th grade? Was it something
   I read somewhere once?.... and then deconstruct it. Often it
   turns out the wall was in my imagination. Once removing the
   imaginary wall, then you're allowing yourself to *really* think
   differently; to make connections that seemed impossible before.
   Getting past that impasse only seems difficult; but I know it's
   doable. And once you allow yourself the right to think how and
   what you want, you start to find ways to make things actually
   happen. The methods you discover may end up being unorthodox,
   but that's what you get when you travel roads that only you are
   going down.
