Imagine a world where almost everyone wakes up inspired to go to work. This isn't a crazy idea. In many successful organizations, great leaders create environments where teams deeply trust each other. Today's workplaces tend to be filled with cynicism, paranoia, and self-interest. However, the best organizations foster trust and cooperation because their leaders build what Sinek calls a Circle of Safety. This separates the internal safety of the team from external challenges. Everyone feels they belong, and all energy is focused on facing the common enemy and seizing great opportunities.
