STRESS! So Misunderstood...Yet, So Popular!!
What we have not learned yet is that stress is a result of a real or perceived package of a THREAT plus a CONFLICT.
The inability to manage stress is the direct result of no training in self-awareness. Unfortunately, it is not taught in schools, not even in graduate schools and unless your employees work for a bleeding-edge business, they will never learn to effectively reduce and manage stress. In fact, we do not want to get rid of stress altogether because it keeps a fire lit - it is when the fire gets out of control and turns into a conflagration that it becomes a problem, as then everything melts down.
Mindfulness and Meditation (MFM) techniques provide significant, scientifically proven,  release and control of stress. They also clear the mind, sharpen focus, and have been proven to lower blood pressure! These trainings can be used to begin the path to self-mastery. Would that not benefit your top performers?  I think so. In fact, I know so.
