Neuro Linguistic Programming or NLP as it is popularly called was developed in the 1970’s as a way to theoretically take everything that you learn and experience and evaluate and change an outcome by adjustments of beliefs, values and emotional states. It sprang forth from the minds of those learned in mathematics and the Gestalt psychological theory, but has become a popular method of therapy in its own right. 
It works by allowing you to determine what the beliefs and values are that you have had taught or developed on your own that place barriers to your ability to reach full potential in life. You enact changes by simply creating beliefs and values that are more in line with what you need your outcome to be. If you want to own a mansion as an outcome in your life, then you simply determine what the beliefs are that keep you held back in reaching that outcome. Is it money? Then you need to change your beliefs about money. If you believe that you are unable to have lots of money, it will be hard for you to ever reach that goal. If you change that belief and adopt a new one that says money is highly valued to you and that you CAN have a lot, it will come through diligent effort. 
This doesn’t mean that you will have a magical drop of millions of dollars into a bank account in your name by simply changing a belief. It means that you have removed that mental barrier that your sub-conscious mind has put in place that limits your ability to find the ways to make the money you need to own a mansion. The possibilities will then become clearer due to sharper focus and the belief that you CAN. 
There is also another factor that takes control of your life and makes keeping focus and possibilities limited. Your emotional state can keep you keyed up and unable to stay on target with day-to-day tasks and goals. What if you could control your emotions? How much easier would that make your life and ability to remember things? Being able to eliminate a lot of the stress and anxiety that is brought on by sheer emotional fluctuations at times will do you wonders when it comes to sharpening your memory skills. The calmer you are, the easier it is to focus your energy on the things that are really important to remember.
