"manipulate" is the wrong word bor.
And honestly, NLP - at least the NLP that works well with people - is a VERY complex system. Can't be executed properly with a few lines and 5 minutes spent on wikipedia. I've read a few books and still don't fully understand it.
Still, good for you for learning about it. The way I see it, there's 2 types of people in the world. Those that just "do" without ever stopping think why they are doing and those that take the bold and somewhat scary step to learning why they do and what effects their actions, words and movements have on the "external" world.
Obviously it is MUCH easier and safer to call any type of psychology or sociology "bullshit", cause it takes people out of their comfort zone.
