If you were excused from any worry about raising money from a prospective donor, what conversation would you strike-up?  How would it feel to speak with a person, free from the pressure of securing their financial support for your cause?  What questions would you ask?  What would you share?  How long would you be willing to speak with this individual?  

Why not try it?  Have a real conversation with another person who supports your cause.  Avoid the FAQs and mission statement (unless they ask).  See if the interaction is remarkably different or the same.
