Your ideas: Simplify. Edit. Refine. Challenge. Thrash. Halve. Then halve again. 

People want the core of what you are saying. They want it objectively communicated alongside evidence of its use, application and intended impact. 

When you want to change someone with your ideas refine them to the point the evidence for their existence can be seen immediately. Transport your audience with a clear rendering of the change you see that lies at the core of the ideas you spread.
