We all worry so much about having our writing rejected and we feel unsure of ourselves.
This is called the "Can I do this?"syndrome. The problem is we all have to face rejection, so forget about the idea of perfection. Many authors use writing prompts as a warm up exercise. Check out Writer's digest daily prompts, at zackarypetit.com. There is a free download and other useful information.
Kelly Stone, author of Living Write, advises that we write for ourselves first. I find that using writing prompts helps avoid the blank page. For many writers blank pages create a fear factor. Another thing some people find useful, is to just write for 5 minutes using a timer. You might be amazed at how far this can take you--so remember don't throw stuff out.
I keep a journal of everything I write. I don't throw out anything because every writing problem can be fixed. In Revision and self editing for publication, Bell advises to Repeat often: It can be fixed, and it is a good idea to place this in your writing space where you can see it everyday.
Another way to avoid the blank page trap is to write without editing until that section you are writing is finished. I love editing my work because it gets better each time I rewrite. When I am satisfied with the section or scene, then I move on. Pre- planning is a good habit to get into because it programs the subconscious and prepares it for writing everyday.
I hope you have found this post valuable. What helps you avoid writer's block?
