I started Chapter 3 of my thesis this week, this one is on the Stratford tramway itself - why it was built, how it was operated, how well it did et cetera. I've made good progress through the week and got up to a couple of thousand words already.
One thing i did do this week is upgrade my word processor (Apple Pages) from 09 to the latest version. I really shouldn't have done that. Endnote no longer works properly, luckily i only use the Pages integration as a short-cut to search for references so i can do this directly from the client, its no more than an inconvenience. Some of the other changes to Pages are a bit annoying, such as the word count is no longer in the status bar but has to be floating over the page. No matter where you put it it will get in the way at some stage!
Hint for future thesis writers, DO NOT change your word processor half-way through.
