If It Ain't Fun, You're Doing It Wrong!
I learned that lesson from one of my good friends and mentors Dr. Jeff Johnson, DTM.
Every Toastmasters club to which I belong embraces that philosophy. We make having fun an integral part of every meeting. My clubs have two success criteria: 1. Did we learn something? and 2. Did we have fun?
Two ways you can have fun is via having meeting themes and through Table Topics.
