I am memorizing 5543 digits, I every day adding some, until now I memorized 1177 digits, I do it with natural memory, because its easier to me like this, the memory techniques and aids are difficult to me, I think except the ease to me, I prefer the natural memory because of faster recall at least to me, because no conversion, in palaces, association and mnemonics I think always there is conversion for example between numbers to letters to numbers, but with natural memory its direct.

the downside is the amount possible to add to memory every day,

i want to know what does it means that after many tries with methods, its just easier to me to use my natural memory, and I want to know if its normal.

i also want to know why I succeeding just with the natural memory and not with the techniques,

thanks in advanced
