It doesn't stop at martial arts though. What about meditating, or Buddhist practice? We cannot rush enlightenment. Our mind in meditation and practice is almost like our limbs when practicing martial arts. The mind is a weapon but also a reservoir. When we rush anything in life we feel exhausted, stressed, and incomplete. But if we take things one breath at a time, focus on what we're doing, and don't rush for results, we very often will find the the outcome is much more rewarding and qualitative.
So I'd like to remind everybody (including myself), to breathe, center, and take things one step at a time. Slow and steady truly is the Way.
