Take a piece of paper and draw 30 circles on the paper. Now, in one minute, adapt as many circles as you can into objects. For example, one circle could become a sun. Another could become a globe. How many can you do in a minute? (Take quantity over quality into consideration.)
The result: Most people have a hard time getting to 30, largely because we have a tendency as adults to self-edit. Kids are great at simply exploring possibilities without being self-critical, whereas adults have a harder time. Sometimes, even the desire to be original can be a form of self-editing. Don’t forget–good artists copy, great artists steal.
