Five Ways to Hold the Right Kind of Attention

I like these three things that John mentioned, for you are letting the other discover the answers themselves and making it more meaningful to themselves and you also learn a lot from what they say. It is a win win situation.
1. Embrace mystery - Frame really gnarly problems that are relevant to you and need to be solved. Help people to understand why these are such significant problems and why so many people have stumbled in trying to solve these problems. It probably will not attract the people looking for easy answers or silver bullets, but it can attract those who are naturally curious and looking for stimulating challenges.
2. Focus inquiry - Don't try to suggest answers. Frame interesting questions instead. Help people gain a foothold by posing questions that intrigue and motivate them to start investigating the mysteries that lie ahead.
3. Excite the imagination - Provide some "what if?" scenarios to illustrate the possibilities that await those who manage to come up with creative answers. Paint the pictures but make it clear these are only pictures. Stimulate people to pursue the questions with a lot of energy and creativity.
