You may be hating this working paper, but it's got to get done. It's OVERDUE at this point, something unheard of for you. The sooner you get it done, instead of staring at the interwebs, the sooner it will be off your plate and you can work on your book review and article referee, both of which are going to be a lot more fun. Ok? It's a working paper, it doesn't have to be perfect.
