Tirrell: So true, but what many have not learned is that they can exceed their perceived limits if they truly want to. You have to know this from experience before you can consciously alter and expand your old perceptions. When a student/instructor is stretched to the physical limits, like you are, it is very difficult to do that, and usually leads to too little sleep, which has many negative results. I will always be looking for ways to help students want to exceed their limits, because, when they do, then they will develop more efficient ways to learn and expand what they can accomplish and also get better at prioritizing their time.
