Arianna Huffington on Key Qualities of Leaders

Good leaders would need to have less fear and more empathy than many of today's business leaders have, Arianna Huffington, founder of The Huffington Post, said in a speech at a business conference in Helsinki.

“Fearlessness is incredibly important because so often leaders don’t take the risks they would need to take in order to succeed," Huffington said.

She stressed the role of teamwork and empathy for the leaders. "I feel increasingly that we need to work in teams. Having a team ... where the leader has real empathy with what goes on with the people, with their needs, not just members of the machine, cogs of the machine, but also as real human beings, is key in terms of the culture."

She said her worst business decision was linked to keeping 'a toxic' leader at the company for too long.

"The end of the story: we have a policy at Huffington Post, which is: 'No brilliant jerks allowed'. We had a brilliant jerk in a leadership position. He was brilliant, but he was toxic. They are people who are very good at their job, but they destroy the culture of the business," she said.

In 2005 Arianna launched The Huffington Post, a news blog and site that quickly became a widely-read publication. In 2012, the site won a Pulitzer Prize for national reporting. Huffington is also the author of 14 books including, "Thrive: The Third Metric to Redefining Success and Creating a Life of Well-Being, Wisdom, and Wonder."
