the secret of remembering words
Memory is like a muscle, it atrophies if it does not work. Each capacity/faculty that is neglected tends to weaken and eventually disappear. So it must be constantly stimulated. The best way to do it is to repeat continuously. If you want your memory to work well, make it work a little bit everyday. The repetition of an operation has a cumulative effect whose main goal is that of forcing information into our brain without us making deliberate efforts.
