My apologies if this seems blunt or if i make a mistake, simply my internet etiquette is shall we say less than refined.

What exactly are the possibilities of NLP?

Can it ilicit changes in my mental capacity?
Could it make me concentrate/think more logically?
Can it make give me something that I dont already have, say like writing or musical talent?
Can it be used to win friends?

Thanks for taking the time to read. Any answers/advice are most welcome, as i have literally just joined the community today.
