the reason is that we don't use the best techniques to remember things . dominic was not a bright student infact he was less then an average student as he had dyslexia . but still he won 8 times world memory championship because he came to know the techniques and principles which works the best for our brain to remember
1: imagination
imagination and memory are strongly connected to each other . so if can imagine the things which you want to remember then you will be more likely to remember it . e.g if you want to remember a word apple then imagine you are holding a big red color apple . which tastes really good and has a good smell. here if you notices i used many human senses in the imagination like smell, taste , touch etc . because including senses makes the word more memorable .
2 : association
association means connection between two things. we are more likely to remember things which are connected to each other .
3 : Nutrition and Exercise
If you want your memory to work at its best, you should get good nutrition and do plenty of exercise on a daily basis. Foods that can sharpen your memory include blueberries and spinach. Aside from this, you can buy some omega-3 fish oil tablets for enhancing your memory power. Doing exercises at least 3 times per week is recommended. You can also join a good gym.
4 : Trust Your Memory
According to Ben Pridmore, a World Memory Champion, you should learn to trust your memory if you are struggling to sharpen your mind. All you need to do is trust your memory. Don't think that your mind is not powerful enough to remember stuff you want it to remember. With time, you will see amazing results.
5 : Avoid Negativity
Most people just don't think positive. You may have heard your friend say, "Man, I am not good with names." If this is you, you have to get rid of this cancerous thought. What you believe about yourself will make a huge difference. You should encourage yourself from time to time. If you lose heart, you are not going to go anywhere. This is the only way of getting results. On top of that, negativity will kill you and may make your mind even weaker. Positive thoughts will hone your mind as time goes by.
