I ended up getting all three chapters done yesterday and feeling very slackful, still. Today I got another chaoter to do and did it, but all of the other chapters are being worked on.
And I wait to hear back from people about more work to do. Luckily, the real work should be starting this week. My co-worker and I get trained on InCopy supposedly either today or tomorrow. And we are supposed to have actual files to work on by the end of this week. We'll see what pace they come in.
But, for now, I tread water. Lunch in half an hour, so maybe there will be something for me to do when I come back from lunch.
