I strongly believe that silence and contemplation are a writer's best friend. Without them we cannot explore the world around us or our own deepest emotions. It is that contemplation that adds depth to our writing.
As I don't think I can say it any better, I encourage everyone, but especially those who write, to read this editorial from Indian Country Today.
I haven't read the book he refers to, but I just ordered it from Amazon and look forward to reviewing it.
