Yes, everyone can draw using stick figures

Drawing or diagraming information you want to explain helps everyone understand it better, including you. When you sketch using stick figures, or flow diagrams, or a mind maps, or any way to help visualization, you will be able to show as well as verbally explain. The process of doing the diagram helps you simplify the ideas in your own mind. The process of explaining using a diagram helps others understand, and later remember, what you showed them.
