Unless you're raising funds for babies or puppies, you're sunk. Right?
I have weird news for you: For every organization wishing it could talk about hungry babies, there's another one that's grown so sick of talking about hungry babies that they're searching high and low for some other way to raise funds. They're tired of it. They think it's cheap, old-school, and not a full picture of their work.
If you're fortunate enough to be able to talk about emotionally powerful topics like babies or puppies, count your blessings.
If you're not, it's up to you to make your cause sexy. The offer you don't have is the one you desire.
