The three fundamental principles underlying the use of M-nemonics are imagination, association and location. Working together, you can use these principles to generate powerful M-nemonic systems. Imagination is what you use to create and strengthen the associations needed to create effective M-nemonics. Your imagination is what you use to create M-nemonics that are potent for you. The more strongly you imagine and visualize a situation, the more effectively it will stick in your mind for later recall. Association is the method by which you link a thing to be remembered to a way of remembering it. Location gives you two things: a coherent context into which you can place information so that it hangs together, and a way of separating one M-nemonic from another.
