Writing, on the other hand, allows me to make more jumps and smash thoughts
together even when they are not discussed in the same sentence. You might talk about X-Y-Z-A-B-C-Y, and I can lump the Y's together by simply smashing some text into the margin. Or I can draw lines and arrows and conceptually group things with circles and squares. I can also doodle. I can't draw at the computer without finding a different application that breaks my chain of thought.
I came across this in a post of Angela Booth's titled: Writing is thinking: switch to pen and paper and use both sides of your brain.
