If people had the attention span to sit for a few hours with your work, then certainly it would speak for itself. But, they don’t. Still, if they were curious to learn more, or knew how to help you, they would. If you experience a reluctance, hesitation, or fear of telling people about your work, it’s even a greater reason to try. The more reluctant you are to talk about your work, the more potential you’re blocking up.
Derek Sivers writes in Your Music, Your People, that when people ask you about your work, giving a boring answer is rude. I wouldn’t go that far, though I would agree that even just a minute of preparation could help. Sivers writes, “Before the conference, come up with one interesting sentence that says what you do—including a curious bit that will make them ask a follow-up question.” He gives the example of, instead of saying “I’m a bassist,” introducing yourself as “Bassist of the Crunchy Frogs—the worst punk bluegrass band ever. We’re headlining the showcase tonight. Our singer is a pirate.”
If I were talking about my book, for example, I wouldn’t say, “I’m an author,” I’d say something like, “I’m the author of Creative Doing, a book that debunks the biggest lie in creative thinking. It has 75 prompts to make the reader more creative. It’s the only book with a shape as a mascot.”
