I have attended the NLP Practitioner course given by Dan Olson, and I have applied what I learned in sales with tremendous success.
I noticed a stronger reaction in prospective customers, and a noticeable difference in what I call influence power. People came into rapport and remained in rapport longer. Sales have increased.
I also noticed that I could direct the state of mind of customers to points I chose, and then intensify the positive white skillfully eliminating negativity in the Sales process. Even when faced with negative oriented people.
I would recommend these courses for sales, and his other courses on self-improvement.
