I have that big damn book contract specifically because my publisher knows they can rely on me to turn in a pretty good book once a year and not be a pain in their ass while I do it.

There's an old saying in the arts that if you want to be professionally successful there are three requirements:
1. You have to be good;
2. You have to deliver on time;
3. You have to be nice to work with
You can get away with any 2 out of 3, they say. But I always bust my arse to be 3 out of 3.
