Sitting on the tarmac at BWI, waiting for the engines to kick up and take me to Atlanta and I suddenly think, "What the hell am I doing? Am I really doing this thing?"
It is a moment of pure panic, now or never, do or die- are you in or are you out? I search my mental pockets and, in wonder, I wonder if I really mean this. The engines kick up and I realize that yes, yes: I do.
