For me, writing is a miraculous process. It's as miraculous as Spring itself, when buds arise from frozen ground and greenery leafs out from wood that's hard and unyielding.
For 50 years I've been writing almost daily. I'm driven not by expertise but by my own bafflement about many things — some of them "in here" and some of them "out there." Every time I write, I'm surprised by what I discover about myself and/or the world.
