My latest set of revisions have arrived. In some ways they are challenging, but in many other ways, they are easily doable.
I do hate it when my editors use the pat phrase -- I know this looks like a lot of hard work. Actually for me, revisions are the fun part. The hard work is the waiting. Finally with revisons I have some sort of direction and can concentrate on what works and what didn't and finding a way around my editors' concerns.
The point is that they do see the potential in the book and think it could be a very strong book.
It is an odd thing about writing -- the challenges for every writer are different. What is hard work to one is plain sailing to another. The important thing for me is that my editors have the faith in me that I will get it right.
