Brain mapping is essentially the act of recording a brainstorming or planning session in an organized diagram. Start with a general idea relating to what you’re trying to accomplish — your central node — then just start throwing up related ideas, connecting them to the node that inspired them, and building nodes upon nodes. Sometimes it’s chaotic, sometimes you’ll be sitting in dead silence, but in the end, you’ll have a vast tree of related ideas, branches upon branches, all leading back to your central theme.
