Wow opens their mind. Aha changes their mind.
Both are better together.
Aha moments can’t happen when your audience doesn’t pay attention. Wow moments are great at getting you attention.
But wow moments get you only half way there. After all, what use is it when people cheer about what a great show it’s been when what you actually want them to cheer for is your idea?
When you’ve opened the door, walk through and take your audience all the way to a profound aha moment.
