Are you green and growing or ripe and rotting?

We are either green and growing, or ripe and rotting.

Too many people think of education as a means to an end, rather than realizing that growth is one of the most essential elements of life.

When we are learning and growing, we are not only better prepared for the challenges and opportunitites of life, but we are motivated, dedicated, excited and alive!


I have been a Blackbelt for about 35 years, a student of leadership for almost as long, and have run my professional martial arts school for near 21.

I have been a consumate student and teacher of leadership for many years.

But when the pandemic hit last year, I doubled down like never before. Something inside me innately knew that the challenges of that chapter were an opportunity to get bitter or to get better and, of course, our KMMA Leadership Principle that “Everything Happens For A Reason And It Serves Me Well.”


I read, thought, led, sought, learned and grew more than I had in a decade.

That period yielded me not only new leadership growth and knowledge, but new mentors, the virtual dojo and our google classroom, I wrote a book and we created the new and improved Blackbelt Leadership Training Course, which is the best and highest manifestation of the vision and mission I had for our dojo years before than we’ve ever offered.


We continue to grow and have begun to reap what we sow.

I am grateful-

and also still hungry, green and growing!


I am also grateful for and excited that we get to help so many other great students do the same!

Youth, teens, adults and whole families are green and growing together at KMMA!


This morning, ask yourself that honest question.

Are you green and growing or ripe and rotting?

If the latter, you can change that any time you choose.

The great thing about learning and growth is that it’s not too late to start again!
