Definitely I question why I train in aikido. Moreso when I reach a difficult patch in training, or when I feel like I'm not getting anywhere.
But I also question where I want my training to take me. And what goals I'm trying to reach in training. Now that I'm getting closer to black belt, I'm questioning what it will mean to have an explicit teaching status in aikido.
I agree with Janet in that questioning where I am and what I'm doing keeps me from loosing my enthusiasm, keeps my training going forward instead of just being rote body movement.
