"...though it cannot hope to be useful or informative on all matters, it does make the reassuring claim that where it is inaccurate, it is at least definitively inaccurate." Douglas Adams, _H2G2_

I've embraced this. Yes, by gum, I will stand in front of a room full of people who have paid thousands of dollars each to be there, I will plow thru the material with gusto and enthusiasm, I will create content on the fly if I have to based on my experience and skill, and if I make a mistake or slam into an embarrassing dead end then I will accept it and use it as a teaching moment to explain that even the best make mistakes or get stuck and that I'll get them a correct answer ASAP and in the meantime we will either start the topic over or move on to the next one. This is reality, this is me, this is what real developers have to deal with, and I'm not going to apologize (per se) for it.

No fear. No apologies. Do the best you can in front of an audience because you love the material. If you're going to be inaccurate, then be _definitively_ inaccurate.
