Find an interesting two-dimensional object (a drawing, painting or collage). Carefully look at it. What would you most like to draw? Where will you begin?
Using light pencil strokes, begin to describe what you see. The goal is to sketch the most important elements in the composition and show how they relate. What is big? Little? Overlapping? On its own?
What happens if you start your drawing from another spot? How would you do things differently? Try it.
