I heard that we aren't supposed to DO a technique, but we FLOW into one.. but many times when training, I as a beginner, find myself in a position unsuitable to do the technique Sensei is teaching. I wanna know what you do when that happens (if ever), would you flow into a different technique or stops and start from the beginning? or is it just me??
As a more advanced student, it would be a good idea to do something else. You don't want to be in the habit of giving up and starting over.
As a beginner, though, your repertoire of alternatives is somewhat limited, plus you need to learn how to get into the right position for a given technique. So you might need to start over. But I'd suggest asking your teacher for his advice: it might also depend on what he is trying to teach at any given time.
