Susan Scott wrote about changing the world one conversation at a time in her book Fierce Conversations - we all know them, the talk we should have with someone but it sits there unsaid.
In this TED talk she turns her attention to leadership. Her 19 minute talk is humorous but with a deadly serious message for all of us about the need for radical transparency.
She explains 3 apostrophes she had (you have to watch it to understand!)
If you are pressed for time, the first 5 minutes will still entertain you and challenge your thinking.
I cannot recommend this one enough and I hope that you are moved to start changing your world one conversation at a time!
