It's always a slightly uncomfortable moment, you might say.

As I wrote this book I went through so many moments when I felt completely vulnerable. But at the same time there were other moments when I felt excited, free, and happy to at last let go of my past.

And when we are forced to be still -because we're in line for something, or waiting at a doctor's appointment, or on a bus or train -we often get antsy, and need to find something to do.
