Dear Meenu,
Nothing in this world will work for anyone in a jiffy. Even to become a better skilled magician, one has to practice, practice and practice. Have you ever noticed, that even mantras recited only once do not yield any results immediately. It has to be recited many many times.... . Here the only catch is the belief. But unfortunately our minds are so fickle, that they oscillate always and tend way wander making out our all efforts go in waste. Even the Asuras in order to get their boon from their desired deities do hard penace and only after so many sacrifices they get what they want...
NLP is a wonderful tool and has to be applied in a right way and in a right manner.
Best of luck...
