It takes significant time for insights to percolate in a group.
The way it works is not that as soon as someone shares the insight it instantly realigns people.
It takes time for realignment to be absorbed.
For insights to percolate and be digested for a single person and as a group.
Let the insight marinate.
As people sit with it, they'll understand it better; they'll have more conversations with others that help it land from different angles.
If you get impatient about how long the insight is taking to diffuse, you'll ratchet up the impatience, and make it significantly more difficult for it to take hold.
Even once someone's mindset has been realigned, it takes time for their actions–and the output of their actions–to manifest it and accumulate.
Be patient.
