One of the books I’m reading is Moonwalking With Einstein, which is a book about memory competitions. It’s a great book and really breaks down memory systems and why they work. It doesn’t really teach memory systems, but it’s a great overview of different techniques.
In the book in there’s a mention of creativity and how people with good memories tend to be more creative. Then it basically breaks down how creativity works in less than a sentence. I’m paraphrasing, but the book says, “creativity is to be able to connect two unrelated ideas”.
I totally agree with this. The better you are at connecting two ideas the more creative you are. That’s what makes a joke work, connecting a set up an punchline. That’s what makes a magic trick work, connecting a prop with an effect. Of course there’s also the craft part of it, where you turn the two ideas into a workable chunk of material.
The better your mental file cabinet is, the more ideas you’ll have.
