Martial Arts Teachers, Be Mindful of Your Most Important Power: The Right Words at the Right Time.
Every single student you come in contact with is an individual with unknown yet enormous potential to do good, to inspire others, to care, to help others, to invent and create, and to carry on --and advance --the very teachings that caused you, the teacher, to dedicate all (or part) of your life to passing on the things you love about the work --and life.
Be mindful of how you interact with your students --be aware that one simple word or sentence can alter the course of their lives. A pat on the back, a word of encouragement, a suggestion that they're good at something, and/or praise for whatever they aspire to or are doing in their own lives; those things are your greatest gifts.
Approach every class and/or event with that in mind --and be one of the (hopefully) many people who boost their esteem, who set examples of how to get sh** done, of how to overcome obstacles, and of how to be a giver, rather than just a taker.
Encourage them to aim high, to be change-makers, and to take the highest road they can imagine, as all of the kicking, punching, and grappling isn't for the purpose of teaching them to fight, it's a delivery system for those things which make us more human, more compassionate, more resilient, and more able to help the world be a better, more peaceful, kinder, and healthier place.
And...I should add, I/we already know you're not a perfect instructor --or a perfect person. Your life, like mine, will be littered with low-points, of failures, and of things you probably shouldn't have done. Nevertheless, all of it, bad --and less than your best, doesn't diminish the fact that there will be many, many times and places where you find yourself in the perfect position to empower someone who is ready to be empowered. So...every morning, rise to the notion that you have an endless amount of potential to inspire others to be the better person you yourself are practicing/striving to be.
