For Valentine's day this year, I hosted a Zoom call for professional coaches who are all single and looking for a partner. These are people who know how to communicate well. We had folks from all over the world. The person farthest away was in Asia and the closest person was at my house.
I used the Icebreaker Starter Pack and the effect was awesome. I don't know if any romances took root that day, but every one said they had a great time learning about each other. We had some deep, meaningful conversations inspired by the cards.
I would totally make my Icebreaker Starter Pack and Deeper Talk regular tools whenever I need to build rapport quickly with a group or individual.
