I don't play music unless I'm driving, I don't have the TV on unless I'm watching my specific shows (and usually alone so there aren't any interruptions), and I don't use an iPod unless I'm running.
I prefer the soundtrack of my life in most situations. Whether that be the zrrooom of my iPhone alerts, or the typing sounds in my office, or the voices of those I love talking to me and near me and about me. My ears are always open, ready to receive intel.
And when there isn't noise? When the zrroom is quiet or the DVR has been emptied or the people I love are busy doing more important things than entertaining me? Then it's quiet and I don't mind it. Does my mind ever quiet? No, not really. But that's okay too.
