Cool infographic Dale! Did you know that there are assessments and evaluations that can not only tell you which side of the brain you are, but can also help you to understand how that effects your style, reactions, etc. 
 
Even better than that- you can then DO something about those things to help you become a hybrid left/right brain. 
 
MBTI, DISC, all are scientific processes that are used in creating persona modes. Once you know your type, you can recognize and adjust your style to suit someone else's. 
 
I call it the anti-bull-in-the-china-shop approach. hehehe. 
 
But really, this is why I became a marketer. Maybe I should have been a therapist. Why people do the things they do, how they make their decisions, I find it fascinating. 
 
Like it or not, we have have a little sales person and marketing person in us. Likewise, we have have a left & right brain.
