Are you a left-brain person or a right-brain person? Which type is best for success in business and life? While left-dominant brains focus on details and numbers, the right-dominant brains see more of the forest than the individual trees. To be successful in handling life’s challenges, business, and projects, you need to see the world from both a left-sided and right-sided angles. But you can’t be both left-dominant and right-dominant at the same time. Solution? If you are more of a lefty, then get a righty partner who can complement you. And vice-versa.
