Plough your own furrow

I left the  dentist feeling very good as the dental pain I had been experiencing was diagnosed as referred pain from a sensitive but sound wisdom tooth and not a failed root canal filling under complicated bridge work I had done a year or so ago.  I spent the rest of the day editing some writing I did quite a few years ago, an extract of which I submitted to a local publication.  In the afternoon I set off to find a blip but nothing really caught my eye except this tractor ploughing.
