Hey dude.
About nlp and subconcious communication in language, i suggest you read the stuff from Ross Jeffries. I do warn you, it takes some practice to be good with it, but from past experiences, i can say that it has a good effect. You should see it like the wind that is blowing forth a sailboat. Always keep in mind that you command the direction, but in the end, she picks the destination.
I know it works, but different people in different situations react in different ways. Dont expect that it will do all the work for you. when the 'direction' is set, you still need to bring up some guts to take the wheel, as matter of speech.
But, it can be done
. cheers!
