Call your best friend and talk for almost an hour about a little bit of everything and a lot of nothing.
Laugh a lot.
Get the validation you shouldn't need, but, ah, well.
Get over yourself. I want to be the perfect teacher already. I'm enjoying my "small" African American history class, but the students in my large survey--which is primarily lecture interspersed with brief discussions (usually analyzing various audio and visual clips)--just aren't engaging like I want them to for the most part. Some days they ask the best questions; some days they look like zombies.
Initially, I worried about it on my own, not wanting to get ideas from my colleagues because I am so determined to appear like I have it all down pat. But I talked to a couple of people in my department and found 1) other people are trying to figure out how to best teach and reach students in the large classes 2) I'm not the only young(er) woman to have to pull a white male student aside and say, "The way you are addressing me before class is not appropriate and it will stop now" and 3) I am not the only new professor ever to have to write lectures for classes further on in the semester--honestly, I made it up to the Depression during the summer and I did teach post-45 in the spring so I can cull from and expand upon some of those (I'm good for the social movements of the 50s and 60s and the early Cold War, for example), but I still need a stronger WWI lecture, a good WWII lecture, and I want to write some killer ones on society and culture in the 80s and 90s.
I know this is not news for most folk, but it's hard for me to reach out for help and advice--always conscious of being "one of the only-" and so I don't want to admit weakness. But that shit was killing me and I'm so glad I did. Turns out, there's a slight chance that people aren't expecting me to be perfect!
And the last part of the solution--go to sleep, so the terrible, horrible, no good, very bad day can become a memory.
