21st April is the UN International Creativity and Innovation day. It’s a challenging time in the world – on a global scale, and, if you’re like most people, you are facing constant stress and challenge in your individual, personal or professional life too. We need to be at our most creative, innovative, flexible selves if we are going to respond and adapt to challenge, and make change happen. What can we learn from Improv artists - masters of adaptability and innovation?
