If your writing has hit a roadblock, here’s a site that could get it going again. Since your brain is concentrating more on the number of words written, it forgets to edit, and lets your writing flow. The webmaster says:
One Two Fiver is a tool to help you sit down and write. Think of it as a series of stretches for warming up your writing muscles. Start with a single word. Type it like you mean it. Now write two words. Move on to five… Keep typing until you are writing.
