Last week I had the honour of presenting the Gold Duke of Edinburgh awards at Buckingham Palace.  I talked to the awardees about my own journey of development, about the importance of pushing boundaries and always trying new things.  After the ceremony was over, and while we were soaking up the atmosphere in the Palace gardens a young man approached me and asked me a question that caused me to stop and think.  He asked me ‘after all that I’ve experienced through my travels and expeditions what is the greatest lesson I have learnt?’
