On Living and Working is four years old today.When I started, on a warm April afternoon in 2013, I had no idea of the possibilities that writing here would open. I have learned much about myself, and about what I care about, by putting thoughts and questions into words, and making them available in the public domain. And I have started enriching conversations with people from many parts of the world who have contacted me in response to what I've written. It has been an enormous gift to be part of what a project like this can make possible.Today I'm particularly aware of how dependent I am on the support of other people in having all of this happen. From people close-in: my friends, family and colleagues who offer advice and feedback and sometimes have searching questions to ask about what I'm saying. From those of you read, reply, comment and share with others. From those who have taught me, and those who have written the books and blogs, articles and lectures, podcasts and films that have inspired much of what's here. From the countless others who designed, manufactured, shipped, sold, connected and maintain the technologies upon which we rely to communicate with one another so widely and effortlessly. And from all those who guided, raised, fed, clothed, paid and otherwise cared for all of these people in the ever-widening circles of support that surround us.Many of us live in a culture that pays inordinate attention to individual achievement. It can lead us into narrow kind of self-obsession that in turn becomes a sense of entitlement - a belief that the world owes us a particular kind of life, and a particular kind of recognition for our efforts, as if what we do is solely the produce of our own hands, hearts and minds. Today, on the fourth anniversary of this piece of work, it seems to me that we have it the wrong way around.I am, we all are, truly indebted to a vast network of living interactions upon which we absolutely depend. A network that holds us, nourishes us, and makes what we do possible, always - and which we did nothing to earn. In a world so obviously filled with troubles, it is nothing short of a miracle that such support unfolds around us and renews itself minute by minute with such unerring grace.
