Tim Harford is the best-selling author of 'The Uncover Economist' and 'The Logic of Life.' In his latest book, 'Adapt,' Harford argues that we need to rethink the conditions for making progress in science, business and society in a fundamental way: we need to lose our fear of failure, embrace opportunity, and take risks. We need to stop looking for leaders who provide us with safe answers, and stop punishing those with the courage to search for radical solutions. We need to understand that to adapt to the challenges of the future, we must make mistakes - and lots of them.
