An awful lot of time thinking about the details

But it is a lot of work to create an entire world and it was about 5 years to finish the first book, to plot the remaining 6 books, because they were already plotted before the first book was published and Book 2 was started before Book 1 was finished. Yeah, so I spent an awful lot of time thinking about the details of the world and working it out in depth.
