Jiu Jitsu forges friendships in a way I’ve never known. Being involved in an art as intimate as this, where bodily connection is a must, the common cultural boundaries of personal space are broken. You will never see more hugs, high fives, and physical expressions of love than on the mats. Ultimately, this proves to be one of the most fulfilling aspects of our pursuit of mastery. Along the way, we learn to love others as we love ourselves.
