The left and right sides of our brains control different areas of thought and function. The left hemisphere primarily controls our logical and pragmatic thought (and the right side of our body). The right hemisphere controls our creative, spatial, artistic, and imaginative cognition (and the left side of our body). Brainstorming works best when both, imaginative ideas and logical problem-solving skills, work together. Pick a paper and a pen and write your name with both hands simultaneously. This might be difficult at first, but stick with it and keep writing words/drawing things until you get into a flow.
