He hears numbers, turns them into pictures in his mind, turns those pictures into a story...and then walks back through the story, remembering incredible amounts of numbers in the order he heard them. It's a method of training for a man with a masterful memory, and it has helped him win the U.S. memory championships.
For me, a former writer, I find that writing anything down (or even typing it) helps me remember. Repetition also plays a part: I'll sometimes take a script, read it through a few times, and focus on the most important phrases of each sentence. Then, when I step in front of the camera, I'll have the paragraph in my head.
What are the methods to your memory?
