The thing with writing is you really ought to be in a disinterested, childlike state of mind. If you have a workplace mentality, any of the various tensions of social striving, or any kind of instrumental fixation at all really, you may be productive and produce fine work, but you never get the magic. God does not dwell in widgets but only in vacuoles of wasted time joyfully stolen from, and protected against, the powers and principalities.
