There is nothing more frustrating than looking at your computer seeing that cursor blinking at you having nothing come to mind. It is not really writers block. You know what you want to say, you just don’t know how to put it on the page.
That is when inspiration eludes you. I have so many ideas running around in my head. It is almost causing a traffic jam. This is the time that you have to decide to either focus on one project or work on multiple ones.
Whichever of these methods works better for you, it will most likely help to get your mind less cluttered. I find that if I can get some of it down I can focus a little better and then I can clean it up and inspiration then strikes and I can move on and the projects take off.
If I have too much vying for my attention it is hard for me to focus on anything. Inspiration can be fickle. As long as you don’t try and force it, though, it can always be found.
