First, lets call a spade a spade. Mindfulness is not a new phenomenon. Nor is it new in the world of business. It has been identified as a need in both life and business for well over the thirty years. In short, it helps cultivate emotional intelligence. Before you can manage a business yourself -- you have to manage yourself and your life. So emotional intelligence is a must.
For better or for worse -- but not forever; most of your core beliefs were formed during your childhood. This is a critical time, primarily because this is a time when you were unable to reason these beliefs for yourself. You identified with beliefs that were given to you, from your parents, your environment, your peers, etc. These beliefs end up following you into adulthood whether or not they truly resonate with you.
