One of the most difficult parts of Kung Fu training is that 50% of it is training the mind. Most people who come to a gym to workout don't want to be there. That's why there are TV's in front of treadmills. Training the mind to be present and aware can be rigorous but the benefit is that you fully experience life! 

Kung Fu is a lifestyle. Take what you learn in class into your life and live every moment.
