We all started at the same place, and at the same time. Why then is it that we were all over the place after taking just 70 steps?
Simple: each of us is unique. Some are taller than others. Some have longer legs than others. Some are less flexible than others. In fact, with such a wide range of individuals, it would be wrong if we all ended up in the same place, at the same time. The stance of a young boy who stands under 4 feet tall should be a lot shorter than that of a man who is 6'7"!
There are a ton of factors in the world of training. Height. Weight. Conditioning level. Experience. Courage. Too many to really list actually. With so many variables, I'm constantly reminded that training in the way of budo martial arts is always you competing against the face in the mirror. In working toward perfection of character, we are always in search for progress...there is no finish line.
