Confused yet? Me too. I'm mostly through with the check-in paperwork and getting started with actual work, or at least orientation to actual work. Meeting people, background reading, trying to figure out who's who and what's what, what's important and what it all means. What I'm going to be doing with my time for the next two or three years.
I hate this part, the feeling like an idiot part. It's one of the drawbacks of the Foreign Service life, starting over from zero every couple of years. But it's normal, and it's temporary. I just have to read the reports and talk to the experts and push on through until the day when it all starts to come together. And to have faith that, eventually, it will.
