I can't agree more! There was a time when I annoyed my mother to no end because she would only see me with my laptop open and fingers flying!!!
I couldn't go anywhere without it because the ideas were flowing and my characters were speaking nonstop to me to have their story told!

The problem now is.... I had an idea for a story... and I wrote down the first chapter before really knowing which path to take. And now... the thought of delivering that second chapter is a little bit pre-mature, until I'm sure of exactly where I want to go! :)
And for years, I was a stay at home mom that could take a few hours away from teaching and write at just about any time in the day.

And now, for the first time in a long time, I'm constrained by a job that requires my mind and my attention for an 8 hour (or more) block and it's a serious crimp in my flow for writing ;)

But on one of my blogs I state "Read a book, change your world. Write a book, create a world!" So like you.... I can't wait to get back to world building ;)
