Tribes by Seth Godin.

New Birth's November 2023 Book of the Month (and March 2020, September 2021)
Tribes will make you think--really think--about the opportunities to mobilize an audience that are already at your fingertips. It's not easy, but it's easier than you think.

Godin presents the three steps to building a tribe:
--the desire to change things,
--the ability to connect a tribe, and
--the willingness to lead.
