I think I was lucky to come of age in a place and time - the American South in the 1960s and '70s - when the machine hadn't completely taken over life. The natural world was still the world, and machines - TV, telephone, cars - were still more or less ancillary, and computers were unheard of in everyday life.
You have to love what you do. And in order to do that, you have to search your soul to find out what it is that you really are about. And then when you find it, if you're lucky enough to be in a position to do what it is that you love, it becomes easy. I'm blessed that I ended up doing exactly what I wanted to do.
