We start with exercise, which is theoretically the easiest to do, and yet, because of our psychological and physical mechanization, it is actually extremely difficult to achieve in practice. The participants in a workshop or a forum session can try sitting down or standing up, on a chair, on a table, or on the ground. As there is no need for preparation, non-actors have no fear of throwing themselves into it. As they are warned that it is almost impossible to do well, they aren’t ashamed of not succeeding. As there is no compulsion to succeed, they feel free to try it.

The participants are asked to describe a circle with their right hand. Large or small, as they, please. It’s easy; everybody does it. Stop. Ask them to do a cross with their left hand. Even easier. Everyone gets there. Stop. Ask them to do both at the same time. It’s almost impossible. Sometimes one person manages it in a group of thirty people, almost never two. Three is the record!

Variation:

Ask the participants to describe a circle with their right foot, seated (easier), or standing. They do it for a minute. They forget about the foot, still continuing to make circles. Then ask them to write their first name in the air with their right hand while the foot is doing circles. Again, this is almost impossible: the foot tends to follow the hand and write the first name. To make the exercise easier, circle with the left foot and write with the right hand. This is easier; sometimes, people manage it. Why is this so difficult? Pure psychological mechanization since there is absolutely no physical obstacle. So, with practice, it can be done.
