Remain comfortably incomplete, a work in progress. Ask for the voice to participate, rather than for a particular message or tune. Use more verbs than nouns in your invitation, more questions than statements.
Think about points of engagement at every scale of your organization or project or idea. From one person to one million, create an on-ramp for each level of scale at which your opportunity-for-participation operates.
Being really clear about the opportunities you’re creating is only half the picture. The other half is being clear in a way that reflects how well you understand the perspective, the desires, of the one is invited.
Empathize. Articulate. Invite.
