With 17 years of Taekwondo under me, I felt fairly confident in my ability to learn martial arts.  In the short time I have been training with Grandmaster Chang, I have found how little I really know.  He has shown me a whole new world.  Hapkido focuses on Harmony and Ki, bringing your body and mind together.  It is an astounding self-defense system that uses your opponents energy to throw them off balance, and sometimes right off of their feet.  It is a very intricate system, but also built so the same movements can be used with or without a weapon.  This not only makes it easier to learn, but also to retain.  Grandmaster Chang is an Amazing instructor.  I've learned so much from him.  His ability to demonstrate and show you the true way of this art is incredible.  I've never been able to truly sense someone's energy before, but I'm beginning to see it now.  Even in this short time he has tought me a lot, and even become like another father to me.
