Re: Beginners with delusions of grandeur...
Ha, Cito is right on.
With new aikidoists from other martial arts, I like to talk about techniques in terms of their martial art if I know something about it.
It's hard to come to aikido from another martial art, especially since it's a fixed game. If the guy was at another type of school, he could easily establish his identity by doing some measured competing. I know we should begin as beginners, but it there is a valid culture in all athletics (or in most persuits) or figuring out who should be your teacher and who should be your student.
The most amazing thing to see is when someone coming in with this attitude changes their mind and learns to appreciate what you, and aikido, really has to offer.
As a final thought, I was once discussing with a friend how I came to SBK with a similar attitude. Not that I would correct my seniors, but I would counter them, strike them, etc. I apologized to him for that first year of being a bit of a jerk, and he said "I don't mean to offend you, but I never noticed."
