It's a simple action: after every encounter (beverage, meeting, hallway conversation), ask: Who should I talk with next?
I think the only time it might not apply is on a first date that is going well...
It works for job seeking, information gathering, network building, friend making, babysitter hunting, and customer service when they can't seem to figure out what you want.
It takes the onus off you to have to personally know or seek out everyone in the world and allows you to be passed along with a smile instead.
Folks don't always think to offer up the next contact but they're happy to share when asked.
It can be as wonderful as discovering a really great book is actually a series or a tv pilot has 12 more episodes.
Ask for the next connection. Be the hot potato!
