Sometimes you need a "warm up" to get your brain thinking and your fingers moving. Random go-nowhere, means nothing, random post that gets your muse started so you may post better posts elsewhere. When you need a warm up, post something. A roleplay post for any character, any scene, any plots. ANYTHING. Three sentences. Ten pages. Whatever gets you thinking. You do not respond to other posts, just type away until that brain is awake and you're ready to go!
