Have you ever found yourself working on a project - the successful completion of which meant a very great deal to you - where you thought you�d gotten it all worked out nice & neat, just nailed the SOB to the wall, finally, after putting many hours of thought and care and sweat and blood and various other bodily fluids into the damn thing over the course of several weeks, only to find yourself suddenly face to face with a series of unforeseen questions and/or possible hindrances, such that you find yourself almost but not quite back where you started? And it wasn�t enough to make you give up the project, �cause you�re bigger than that, of course, but perhaps you wanted to find a dark, quiet corner somewhere far away from distraction, so you could properly bang your head against the wall?
