I've split of the remedies for the common writer's block into two categories: those that cost money and those that don't. Thankfully, the list for those that cost money is quite small.
Remedies that cost money
In a world where gas prices are above $3.50, thank god for remedies that are free.
1) Free write: One of the first thing you learn in writing 101 is free writing. Put your pen down on the paper and write non-stop for 5 minutes never picking it up. Even if all you write is "I don't know what to write. I don't know what to write. I don't know what to write." Sooner or later, something will come out.
2) Write in a journal: I find that writing in a journal everyday can help get the creative juices flowing because at the end of the day, you're writing. And that's what matters most.
3) StoryMash.com: One of the things I like about this website, is the ability to collaborate with other authors. What I found was that having the ability to write from someone else's idea helped me to get my own. They even have writing contests giving you the idea and concept to start with.
4) Writing Prompts from Writer's Digest: The Writer's Digest website provides you with a list of writing prompts, scenarios you can start from to relieve the sinus pressure of your creativity.
5) Creative Writing Prompts.com: Another wonderful website full of writing prompts to help you out. Just click on any of the 346 numbers to see the writing prompt within. I find that this site works best if you don't pick and choose. Just click a number and write away.
Well, I hope this helps. If I find anymore fabulous remedies (cost or no cost), I'll let you know. In the meantime, I hope you feel better.
