Even if I don't plan to write that day, I write down my ideas in an idea folder. This helps tremendously. Not only does it help get me going on days when I would rather be baking than writing, but it prevents me from ever NOT writing due writer's block.
I do this for all the sites I write for, since some fit the style and formatting better on one particular content site than another. Some days, my idea folder will be bulging. Others, it might only have one or two possibilities. The key is just having these on hand and being prepared for whenever the inevitable writer's block might strike.
When I have exhasted my idea folder, I usually go hunting for more ideas to build it up again. Sometimes this means reading blogs or other articles on my favorite websites. Other times it means taking a trip to the library and reading some new books to help fill my mind with new knowlegde. Simply taking a walk outside can inspire me too. Wherever I find my idea, I make sure to write it down.
My idea folder works for me in preventing writer's block. What are some other tips you use in dealing with writer's block?
