Leadership. People "buy into" your vision, not necessarily all the details. That's what you need for intelligent co-operation, anyway. As far as other resources I believe Toastmaster or toastmaster jr. would be great but it's too far to drive to join for me to find out. Locally the school I believe teaches book reports, show and tell, and the science fair which promote leadership skills because they help you get your plan together and present it coherently. That sounds like the skills you need to develop your vision and get it out there.
That's what I've heard anyway. Funny how I'm always looking for ways to say whatever I have fits what I need.
