Get a mental picture of you?
That question is really creepy and try to make a specific description please.
Photo (Photograph); a picture taken by photography, you use a camera to take a photograph. The term picture includes a photo, a painting, a drawing, or a motion picture. A photo and a picture are generally tangible. But the image is an intangible object, a likeness, an idol, a mental picture in imagination or produced by reflection through a mirror or lenses.
Reading books (even bad books) makes your brain grow big and strong, just like pumping weights does for your body. Reading books can help to increase your vocabulary and broaden your views. Also, books require you to use your imagination by creating a mental picture, and everyone's mental picture is different, whereas videos present the same picture for everyone.
