The first real challenge is to get your mind and your body to work together.
This may sound easy but it is not.
Tai chi does not rely upon brute force or muscular contraction, and your body must move as a relaxed, integrated whole.
The only way in which a student can acquire this first skill is to practice regularly.
It is not enough to blindly repeat movements.
These movements must be carefully performed, with close attention to detail.
Even though you may try your best, your own body might well refuse to cooperate.
Considerable patience is required.
Simply learning the crude pattern of the movements will be an achievement.
And you will know in your heart that your very best looks lame next to the grace of your instructor.
Humility is born of this realisation.
