Doodling is a great way to let your mind wander and explore your creative impulses. Start with a blank page or a clean surface, so that you don't feel constrained by any existing lines or shapes.

It's easy to get engrossed in your doodles and start actually drawing, but you'll notice that once you make the switch, you stop paying attention to the person you're supposed to be listening to.

The aerial artistry of South Africa’s Patrick Davidson has made him a multi-time aerobatic champion and a success in air racing and air shows. Behind each flight is a doodle.

Science teachers may want to add doodling to their lesson plans, say researchers who found the freehand drawing may help students learn science.
