How can I work under these conditions?

For many months - about 24 - my office has been the dumping ground for everything for which we could find no home in the house move. It just can't go on and chucking stuff out is something I can easily do while recovering from my op. Even a little at a time. So, this is the 'Before' pic.
I make no promises on timescale before I can post the 'After'.
