Lately it seems I've been dealing with a number of doors either slamming shut or quietly being closed, locked, and barricaded. The most recent hit me in ass as I was unceremoniously tossed out. What can you do? Shit happens and sometimes we never find out why. (I try not to press my ear to the door once it has been closed in my face.)
You dust yourself off, mentally come to grips with reality and then take a look around. Because you'll never notice a new door cracking open if you're huddled in a corner having a pity party. And usually the new door has absolutely nothing to do with the old ones... it is just a possible path to a new direction.
Sometimes, that is all we need.
