Unlike a runner's high, yoga is cumulative. You can miss a few days, a week or two and the effects of yoga can still linger. For me, practicing at least once a week is necessary to be a normal human. Practicing twice a week increases my patience exponentially. If I practice three or more times per week, my children become hilarious and not so annoying. The shift is 180 degrees. From thinking my children are surely out to get me to finding the humor in the things they do is what it's all about. Yoga works.
