Are you good at math? How about writing poems or painting beautiful pictures? Do you love to sing? It all depends on whether you are a "right-brain" or a "left-brain" person.
The human brain is a truly amazing organ (器官). It's not easy to study the brain, but science is slowly beginning to understand how it works.
The brain is divided into two parts: the left side and the right side. Some people use the left side of the brain more than the right. Others use the right side more than the left.
Left-brain people are good at math, science and reading. They do well in school. They can easily focus on detailed tasks. They like to work independently, and often enjoy studying alone. Right-brain people are more artistic. They love music and singing. They like to be around lots of people. They don't like to sit still.
Mind mapping (思维导图) is designed to use both sides of your brain-mind mapping involves your right and left brain thinking. Our ability to speak and communicate seems to have its origin in the unlikely pairing of the left brain and the right hand.
The fact that you use one side of your brain more doesn't mean that you don't use the other side. It just means that you prefer one side to the other. One way is not better than the other. It only shows the way you learn best.
