You learn, adapt and enhance your skill and knowledge further.Most people simply deem the NLP practitioner certificate as a qualification alone.
Hence, their methodology is skewed to one direction, causing students to be unable to use NLP beyond a narrow set of skills.
If you can't get yourself under control and check your own ability to open up, consider new possibilities and achieve new goals, then what's the point of learning NLP?
Key point is this: keep within a learning group that is diverse and celebrates changes and improvements.
Becoming an NLP practitioner is about hunting down useful skill to improve one's abilities and become more powerful in achieving results. You can also maximize the use of such tools to make a difference in the world.
I've seen highly inflexible and intolerant so-called NLP practitioners.
