Here's a helpful reminder from Damn, I Wish I'd Thought of That! -- You are not your customer. It's an issue for fundraisers, because just as commercial markets are not their customers, you are not your donor:
... whatever you think is interesting is almost definitely NOT what millions of customers think. Remember that you're not your market -- and what you think is interesting is almost definitely wrong. You're the weird one.
Yes, you are the weird one. The difference between you and your donors is so deep, you can count on anything that's interesting to you being unmotivating for your donors.
Fundraisers who grasp this raise a lot more money. They enjoy their work more too.
