I'm actually rather glad that the first few posts about "weakness" addressed the two things I've been thinking a lot about lately: what my students think of me (or rather, what I think about what my students think of me) and the way we have of calling each other out on weakness.
First, a confession: I am the author of the Cowboy Up Post. I called another professor a potential wuss for wanting to quit in the face of a department that doesn't validate teaching as much as she wishes it would. And I'm ready to admit that I got sharp instead of snuggly because she's on tenure-track, and I'm not. Whatever.
Point is, I wish I'd written an encouraging post instead of a condemnatory one. But let's face it--something about our profession, or our society, or the roiling combination of the two, encourages us to present a face to the world, and each other, of self-assured perfection so perfect that one of the ways we score points is off of each other's insecure heads.

And then you realize that being funny and charismatic just feels *good.*
Let's ask ourselves the following in these situations: are our students learning something accurate and valuable from our classes? Do they leave freshman composition even somewhat better writers? Do they leave History 101 knowing at least a little about history? Can everyone who passes Calc 2 do... whatever it is people who pass Calc 2 have to be able to do, so that bridges don't fall down? If you can answer yes, you're doing a good job.
In more advanced classes, I felt okay expecting the students to bring their A game at least twice a week, and by and large it happened. Being a dork at my thing was both funny to them and educationally productive. It's in the introductory, required shit that I found myself compromising my useful dorkitude to make them laugh so that we could all get through the 75 minutes. But at the end of the day, I tried hard to be able to say, "yes, maybe I was a little cloying about the baseball team with the baseball player, but I also made a good point about semi-colons."
We get to enjoy our jobs. We don't have to do this job EXCLUSIVELY because we feel like we "owe" the People of Pennsyl-tenne-sconsin the education of a Land Grant University... as long as you do, in fact, keep the learning process at the center of your teaching, you're allowed to enjoy the fact that you seem cool to the cool kids for the first time in your life. Don't sleep with them, okay? But if the pretty girls or boys (or girls AND boys, for that matter) flirt with you and you like the feeling, and it keeps you from tossing yourself off the building or yelling at your own children or quitting to take some job where you will likely NEVER get to write...so what?
