Some time ago I learned about psychological safety and Crucial Conversations. Since then, I've seen them improving my life.
To test whether they actually work, I did a little experiment in my life. For some time, I played a little game where sometimes I followed the opposite advice to see what happened. And yeah, I saw the conversation quality go down. It really is not inconsequential to have a common purpose and being open to wild takes.
So yeah, I realized how powerful Crucial Conversations and Amy Edmonson's research are and applied them to my life. And naturally my quality of life improved quite a bit.
