Steven Seagal (Take Sensei) continues to have some of the best Randori on YouTube,

... But I just stumbled across this one, in which my worst fears were discussed quite clearly. I freeze. I get caught, and then I seem to forget everything I'd like to think I "know" about Aikido.

And what are the standards to which I hold myself?
1) Never stop moving
2) Be aware of the whole mat
3) Don't get stuck on a single Uke (in our training, we're taught to "finish, and then move on", but it's still bad form, at least at higher ranks, to dwell). Deal with the attack and move on..
4) Be calm. Even if I screw up (which I most certainly will). If you exude tension and fear, so will everyone else.
5) Never, ever, stop moving. (AK's words: "Keep movin' and you'll get somewhere you know")
Some more advanced pointers that I hope to emulate occasionally:
1) line up Ukes so that I'm always the least exposed (shikaku)
2) make THEM look for ME
