REDUCING STRESS AND ANXIETY
Bringing stress and anxiety levels down will do a lot to help improve your ability to remember nearly anything and everything. The problem with enduring and tolerating high stress levels is that it derails the focus and attention to the details that you need to have to really have excellent memory recall capabilities. You may not be able to stop the problems and situations that tend to bring stress on you, but your reaction to them is totally in your control.
Controlling stress and anxiety is simply a matter of controlling your emotional state. That is done by controlling how you breathe, how you sit or stand, how you hold your shoulders and how you use the 80 facial muscles. If you sit or stand with drooped shoulders and breathe really shallow and use a depressed or angry expression not only will you feel sad or angry, but you can feel the tension in your body take on a life of its own. 
If you bring a big smile to your face in times of extreme tension and straighten your posture, breathe deep and slow you will quickly find the tension drain and get replaced with energetic feelings that are far removed from stress and anxiety, This  doesn’t work some of the time, but every time. Being mindful and taking note of when you need to do this is the hardest part of initially employing NLP. The relief you begin to feel will soon have you actively doing it as a routine. Does the immediate release of tension and stress get rid of the problems that brought it on? No, but it gives you the relief you need to be able to focus and get the problems managed. No one can effectively function while they are under too much stress and anxiety. 
How does any of that improve your memory? It is easy. If your mind isn’t bound up with worries and stress and is able to clear itself of clutter, it will be easier for it to recall the more important things it needs to. 
It is also possible that you’re not stressed out or suffering from anxiety. The reason for your bad memory could be the simple fact that your brain is clouded with too many things and too many thoughts. They don’t even have to be negative things, you could be thinking of wonderful things but the fact that there are so many of them means that you forget other things. 
What is required in this case is a spring cleaning of the mind so that you don’t become overwhelmed by thoughts. This is common for creative individuals who have hundreds of ideas coming in all at once. A moment of inspiration creates a situation where the brain gets flooded by ideas and this can displace other important thoughts and information so it is not uncommon for people in creative fields to forget important key details like where they parked their car. Like stress and anxiety, a flooding of thoughts and ideas threatens the memory and creates disorder in the brain. 
Sometimes people put themselves under stress without even knowing it. We often put too much pressure on our brains and this results in memory loss. Have you ever noticed what happens when you’re straining your brain to remember the name of a song or a movie? Despite the name being right at the tip of your tongue you somehow cannot get it to leave your mouth. This is the pressure the brain is often put under when we try too hard to hold onto concepts and work too hard to remember things. The best concept is learning to put less pressure on the brain and allowing a flow of ideas that’s is more relaxed and calm. One thing most people learn from studying is how cramming just doesn’t work as well as understanding the concepts. Cramming is often the method of last minute studiers and understanding is something that comes from taking the time to read and make sure that you absorb the ideas and know the mechanics and not just memorize the facts as if they are words to a song. Some of our struggles with memory are self-inflicted and if we changed how we brainstorm or study we could actually be able to get so much more from our memory. The good thing is memory can be worked on by training the brain and doing memory exercises. 
NLP can also help reduce the stress and anxiety that may be developed from years at school that may not have been the most pleasant for you. Let’s be honest here. School means lots of tests and there is such a thing as test anxiety. Some people do terrible at tests even though it is no real reflection on intelligence. After a few poor performances then it can start a downward spiral of feeling low self-esteem. Those around you may not be very encouraging either. All of this begins to shape a belief system that you cannot remember things for tests, which then begins to grow and expands into life in general. 
The simple use of NLP relaxation techniques could have made all of the difference on your testing performance in a matter of a few minutes. There may be no way to change the past, but you now have some of the tools necessary to make the future better. Stress will never have a hold on you again by using NLP techniques.
