I concur. I too chanced across that Harry Lorayne book in high school and it made rote memorization much less of a chore during those years :) Even now I occasionally use it for phone numbers.

For the others, this is the book: http://www.amazon.com/How-Develop-Super-Power-Memory/dp/0811...

I managed to memorize the forwards and backwards order of half a deck of cards the first time I tried using this book: http://www.amazon.com/How-Develop-Super-Power-Memory/dp/0811...

And then I promptly picked up a new book to half read after life distracted me for a week and I forgot about that one.
