Good Lord, what have I done?

I am so freaking tired after day one of this 2-3 month transition. So, a little worried about maintaining sanity, but the work is already so challenging, it's worth it. I sat through several meetings where I sometimes thought they were speaking some form of Sanskrit, and other times, I spoke it as eloquently as they. I also submitted the last materials for my grad school app, confirmed registration next week, and will have my formal acceptance in hand next week. I had a short spurt of energy tonight, but feel it quickly ebbing, so will log off. Have to be at work before 7:30am tomorrow to see my departing staff member's reaction to how we decorated her cube tonight!
