I need to be focused on writing most of the time in order to make a living at it. Other wordsmiths might be able to put in far less effort and get a similar result, but I need to work at it continuously to keep it flowing and fresh.
The creative aspect of this work is effortless for me. I simply need to turn on the mental spigot in my head. Once I do I’ve access to that right-brained creative writing ability, and can just let my imagination fly. But in the case of grammar and technique, I admit that I have plenty of room for growth, which is why I enjoy articulating these fundamentals of writing.
