I undertook an editing course for a couple of weeks, in order to help get my creative thoughts across more efficiently. It worked wonders for organising my thoughts, and for the flow of my newest book.
Don't be afraid to get up and walk away for a couple of days, or even a week. During the middle section of my current work in progress I became that emotionally drained from the scene I was writing that I ended up having to walk away for three weeks. I worked on the first book to a new series during this time.
I began writing creatively after the birth of my first child. I desperately needed something to keep my mind occupied, so I undertook a creative writing course in 2015. I am happy to say that I have been writing since then.
