The Clear Lessons video library contains more than 500 videos with experts from a wide range of organisations, among them Barclays, Marks and Spencer, and Innocent, sharing their experiences and wisdom. The videos are all just a few minutes long and cover a vast range of topics, including managing people, resilience and emotional intelligence.

"It’s a myth that you have to go on a week-long, expensive training course to become a better leader," says Martin. "It’s amazing just what you can learn in a few short minutes. It’s time to start learning about leadership how we learn about almost everything else these days – via video learning. Video is the perfect way to share knowledge."
