I’ve noticed many other people pointing out how inaccurate this is. This one is just an unkillable myth. Come on people we finally got everyone to understand the “10% of our brain” thing is a myth, let’s get to work on this.
In my opinion, it’s best to be left-brained with a touch of right-brained. It’s good to have imagination, yet the logic and rational thought to get it accomplished. That’s what makes the difference between old hippies who fried their brains and old hippies who founded Apple Computer.
