Give an hour long lecture (all by myself, no teacher present to help me if I can't answer a student's question).
Followed immediately by class (for which I haven't had a chance to prepare, i.e. do the reading).
Followed immediately by my hour long pitch to the department of my new idea(s) for where I want to take my research for the next 3-5 years (a completely different direction than I've been going).
Followed immediately by co-hosting a talk series.
Then to an organizational meeting for TED.
Wish me luck!
