More Insights and Ah-ha! Moments
Doodling—repetitive mark making, pattern making, coloring—is akin to other rhythmic actions (showering, walking, meditation) that relax the grip of the brain’s “executive functions” (making to-do lists and organizing thoughts).
By shifting your attention away from over-thinking, doodling fires up your brain's "default mode network." This is when subconscious insights, improv, daydreaming, and lots of creativity take the lead.
This is why you get great ideas in the shower!
