Mind Map
Thoughts don't come in order; they come as a web.
The mind mapping technique mimics the brain's natural associative structure. It is based on the fact that the brain works not linearly, but as a network. Maps branching out from a central concept make invisible connections visible, revealing relationships missed in linear note-taking.
Tony Buzan, Use Your Head (1974)
Action
In the center of a piece of paper, write the biggest question on your mind right now. From there, write or draw every branching thought, every association, in no particular order.
