Drawing on the Right Side of the Brain

There are certain books that are practically canonical for doing a certain kind of thing. I feel like drawing on the right side of the brain is kind of like that, because i can't draw. The exercise i always remember that was so illuminating to me is to flip through a magazine or a book you've never seen, but flip through it upside down as you look at it. And the craziest thing happens, which is that you start drawing what your eyes see, rather than what you think the face should look like. Is that make sense?
