Sent me reeling. I questioned my intelligence, competance, and state of equilibrium. I spent a long sleepless night fumbling, and tumbling, rocking and reeling.
What to do? I went back to basics. First I went with the premise: I know nothing. That was a bit humbling, but basically true, and a way of touching bottom and starting to work upward. I retraced my steps, went back to the documentation. Going one line at a time. I did a bit of searching, Googling, trying to get myself "smart." Grasping at straws in the wind.
This morning, after a very long, dead-man's sleep, I feel much better. Actually, quite refreshed. Maybe I haven't solved the problem yet, and I have no idea if I will come to a successful outcome, but now I know the contours of the task at hand. I am a bit more comfortable, and slightly more knowlgeable. Baby steps.
