Re: So I taught my first class...
Josh, congratulations! I'm with Jonathon on this one. I was nervous and still feel a little weird about leading class (substitute teaching for sensei). I finally let my classmates nudge me up to the front; I had preferred to stay in line with everyone else to rei in. Hopefully the confidence will come, but I would much rather learn from sensei than attempt to teach aikido.
Carrie P, the education background does seem to help with organization, timing, and transitions between themed warm up exercises and techniques.
