If you want to get published, you have to write. Writing - just getting that first draft out as words onto a page - takes time, and can be a slow and frustrating process. I've found something that may be able to help you.
Have a read of this great post by Rachel Aaron, called How I Went From Writing 2,000 Words a Day to 10,000 Words a Day. Rachel discusses in detail how she created for herself a triangle with three core requirements: Knowledge, Time, and Enthusiasm.
I hope you get something out of it. I personally thought the Knowledge section was most applicable to me. How about you?
