There are many great knowledge products out there to help you learn NLP. These are my personal pick of the bunch.
(Note: I get some amount of commission if you buy one of these products, but I only list the best products from trainers I personally know and respect, because it’s my credibility on the line.)
Jonathan Altfeld is one of the smartest trainers in NLP, and has been a good friend of mine since the late 90s. With a background in expert systems development, he has brought some truly innovative ideas into NLP.
