memorizing is out of the question. it's harder than memorizing a brainwallet. no amount of practice is going to allow to remember it for longer than a few hours if that.If you have problems remembering 12 words for more than a few hours, it does not mean that this is the case with others. People remember whole pages of text, although they may be talented individuals, but it is far from impossible to remember only 12 words if someone wants to. The thing is that you don't learn all the words at once, you learn them in sequences of, say, 3 words that you then connect into wholes after each sequence you remember.
