Fix your vision on a nearby stationary object. Without moving your eyes, become aware of what is in your peripheral vision. Notice how things get fuzzier the further they are from the center. Now, close your eyes and try to recreate the scene from memory. Try to get a vivid image. Then, if you want you can draw it.
This visual exercise will help you become aware of the things that you do not normally see. It also helps improve your ability to reconstruct things in your mind’s eye. Visual skills are an important part of creativity.
