NaNoWriMo or no?

November is getting closer. I have an idea for a novel and the yearly, NaNo event is the perfect way for me to get it written. There are two nagging doubts to overcome.

Firstly: will it be worth writing? I had promised myself to make the next book (this is number four) the best one. To be sure of this I’m creating a more solid plot outline and some sample chapters.

Secondly: is it the right book? Writing a thriller (which is what this is) is something I seem to be able to do. But I feel there’s something different I can do. I feel if I can write the blurb for the back of the book, I can write the book. Perhaps this is a sign that the idea is not ready yet, or that I’m just clueless and not a proper writer.

All these things are possible.
