> How do you add the numbers on landmarks? Do you just have a road sign with 42 miles to x, or a building with 8 windows? It could be anything, what you said would work beautifully if it has occurred spontaneously to you. The key thing is it has to be very very natural to you but may not make any sense at all to others. Example, one of the building I have assigned the number 78 as it is an old building and my father's age is around that. > do all the landmarks need to be unique Again it is a very personal decision. For me currently it is one pair of number per landmark as I did not want to 'overload' my system. But if I think about it now, maybe after sometime when I'm comfortable with my current system I can assign another number to the same landmark... But I'm not going to risk it now :-). If you really want to try it out, start with one thing now and see how it goes before doing for others. Btw, I discovered this when reading 'Moonwalking with Einstein' (referenced by another commentator here). This book was in reading list of Bill Gates couple of years back. To illustrate my earlier point, the title of the book does not make any sense at all, but that series of words is used by somebody in the book to remember certain things.
