People often say to me, 'you are so lucky to have such a wonderful job', and I do have 'the best' job. But it is not luck, it has come through hard work and skill and years of honing my field craft.

What I am lucky for, is to have met such extrodinary people along the way. Not only professional collegues and peers but also, in the locations I vist, the local people that care about the world and are proud to show me their piece of it. I'm invariably treated with real kindness.

Thank you to all of you.
