Just as the physical body becomes strong through regular exercise, so does the mind require regular use to remain strong. Make sure that your personal development plan includes plenty of mental stimulation. One of the best ways to develop your imagination and visualization skills is through reading. As you read, your mind translates the words into images that help you better understand the concepts about which you are reading. Become a voracious reader. Read newspapers, trade magazines, self-help books, and novels; all will contribute to your store of knowledge and to your ability to visualize and more effectively use your imagination.
