Shakespeare wrote, in Richard III, "Talkers are no good doers." I've always loved that, and I've always used it to remind myself that I don't need to fill space, that there's nothing wrong with quietly going about, getting on with my work. Silence, after all, can be far more profound--we don't have words for everything (and, really, thank goodness for that).
In silence we not only find ourselves, but we meet ourselves, sometimes for the first time after a long absence. That may not always be a comfortable reunion, but in time, it will resolve itself joyfully.
That is, if we don't talk ourselves out of the journey first.
