Tae Kwon Do is way more than just movement. It's a way to express yourself and help others grow. For example, today I was helping out in Little Tigers class (they're the best) and I just love working with them because they improve right in front of your eyes. If you tell them something they won't just put it in the back of their head and think, "who am I listening to? A ten-year old?" Instead, they take the knowledge for all it's worth and apply it. Not always immediately, but it comes around. I just think it's so cool how fast they recognize that you're trying to help them and they know that what you're saying can help them improve. As opposed to higher belts / older kids. What I've seen some people do sometimes when I'm assisting with class is, I'll tell them, for example, keep their hands up or not to go on their tip toes when throwing kicks and they just put the information in the recently deleted section of their brain. The moral of the story is that you can learn from any person no matter how big, small, young or old they are.
