Who would be surprised?
When was the last time you surprised or delighted a customer, colleague or boss?
If you did, would it help?
Apple developed a tradition of secrecy largely because Steve saw the extraordinary value in surprising the audience. It creates a rare wave of excitement--remarkable is a byproduct of surprise. Today, they continue to work at the secrecy, as if that's the only element necessary to create surprise.
But of course, it's not.
Surprise comes from defying expectations. Sometimes, we have the negative surprises that come from missing those expectations, but in fact, those negative surprises are part of the process of exceeding them... if you're not prepared to live with a disappointment, you can't be in the business of seeking delight.
Effort matters, sure, but mostly surprise comes from caring enough about your audience that you're willing to fail in your effort to redefine what they expect from you. The vulnerability and intimacy that come from that leap are at the heart of what people talk about.
