Daniel Goleman’s recent book, Primal Leadership, suggests that a coaching style of leadership may best describe the rarest—and most essential—qualities of the quiet leader.

“The coaching style is the least-used tool in the leader’s toolkit,” says Goleman, “probably because it doesn’t look like leadership.”

Like a coach, a quiet leader can achieve breakthroughs by asking guided questions rather than giving orders or advice, and by getting to know each member of a team well enough to be able to craft work assignments to best suit where they are and where they’re going.

Yet it’s clear that quiet leadership is not so much about any particular management style as it is an attitude toward work and people—and life. Keeping your ego in check certainly seems to be a prerequisite, as is giving up your ambitions for being on the cover of Fortune.
