Re: The crux of two ranks having any equality
A Yondan gave me two really good pieces of advice once upon a time.
- You get out of Aikido training what you put into Aikido training.
People have different goals in their aikido practice. So better/worse comparisons are tricky to begin with. Your goals may not coincide with their goals, or your sensei's. Practice with the intensity you want out of your Aikido.
- The best thing you can do is shut up and train.
This was given with a smile in response to a problem within a regional section of our organization. If you aren't on the teaching staff, or the board (if non-profit), then it isn't your place to "break it" to them. Worry about your personal practice.
