I started writing novels in 2006. By 2008, I had stared a half a dozen novels, however, I could not finish any of novels. Well, it was not a writer's block that stopped me from completing my novels. My priority changed and I began writing articles and ebooks for money.
I have been writing since 2001. I have written thousands of articles and dozens of ebooks. As a professional writer, Sometimes I find difficulty with completing my writing projects. However, this not due to writer's block but the lack of motivation. Also real life, i.e. offline obligations.
One of my favorite ways to deal with this is start doing things that I like to do. When I am not in a mood to write, I begin reading. The more I read, the more my imagination is fueled and the more i'm able to write.
