“I enjoyed seeing the in-group dynamics and how I personally behave in a group.”

The confidence to speak up and express your ideas

“I felt more confident and built up the courage to speak in front of 30 strangers.”

“It’s a chance to speak in front of others, without being judged and without judging others.”

A safe environment

“I really understood that we were here to work together and not to judge or challenge each other or to say anything negative.”
