This is Steven Tomlinson's TEDxAustin talk:

Steven is entertaining because he's funny. But there is a subtle edge just under the surface: he earnestly wants you to change. And the change is uncomfortable, routine, and it forces us to confront the elephant in our heads. But this brand of inspiration is worth every tough encounter. In fact, the tough encounters make this inspiration worthwhile.

For the communicators: notice how he ends. Steven dropped his volume, stated his conclusion, and stopped.
