Re: Pro's and con's of asking questions.
On the mat as a student, I was never encouraged to ask questions.
I just mimicked what I thought I saw and came up what whatever explanation made sense to me at the time.
Most of the time, I was wrong.
Later, mostly through reading and after work out conversations, I realize how much of Aikido was the application of the unseen/unspoken principles and the mental focus/intent.
After that, as an instructor, I started offering more explanation and encouraging questions.
I often wondered if instructors didn't want questions because they cannot really answer them.
I have found that students/people who truly understand what they are doing progress faster and go further.
