I certainly have.  In fact, over the near 3 decades I've been involved in interpersonal sales and high level marketing, and  had the opportunity to make these tiny distinctions literally hundreds of times as I've navigated through thousands of interactions.  Over time I developed a passion for sniffing out the "why" behind the biggest successes....AND....the biggest failures, and started to teach...which ultimately has become my life's mission.  I've spent years assembling the information into classes and workshops to help shave time off your learning curve so you can experience breakthroughs that without this little insights, may never happen.   If you've been feeling 'stuck'...let me assure you...you're among friends.  You're in the right place.
