That's what it is. Fundraising is a "Bring your own imagination" party. Little wonder then, that it must be one of the world's worst attended gatherings!
I can write up the invitation in any format you name. I can strategically deploy the words you currently love. I can break up my 'ask' into children's portions or lump them together to sound impressive. I can give you a multicoloured brochure or an academic's document full of jargon.
I can speak to your heart. I can orate to your conference hall. I can make you a jazzy powerpoint. If you gave me money, I could throw it down the drain to make an animated film about my funding needs. I could even write a song and sing it for you, with the refrain: Tum ek paisa de do, voh dus lakh dega! (Or, in tune with our current needs, tum 6 lakh de do, voh 60 crore dega!)
I can share my vision with you in the medium of your choice. Bur if you have no imagination, I have no cure for that but prayer.
