Totally fun - give this quick visual quiz from Brandweek NRX a chance. It's by Peter Rost, M.D. and shows you if you are right brained or left brained.
To me the best part was I could actually see the difference when I focused on using my right brain va. using my left brain.
Just as a reminder: People who are right-brained are thought to be more creative than left-brained people. Left-brained people are more focused on logic and structured activities.
