Nicola Reindorp, who once doubted her own abilities to be a CEO, says we should rehabilitate doubt as a strength rather than a weakness in leaders. "I'd seen my own doubts as negative, disqualifying me from leadership. I had seen others believe the same. But, I asked myself, aren't the best leaders not the ones that say they have all the answers, but those who know they don't? Not those who say they see it all, but those who ask whose perspective is missing? Rather than a deficiency to be hidden, maybe doubt should be seen as a power to be harnessed?"
