This LinkedIn message came last night, in response to a Leadership Keynote speech i gave nine days prior:
The 72-hr challenge was a good kick to start on something good. I was visiting a client this week who spoke very highly of your presentation. She was very impressed, inspired and working (continuing) on her 72-hr challenge 🙂
So, the impact you were hoping for is definitely taking place!
Be amazed and be amazing. The world needs more of that, as evidenced in the unsolicited message above.
