Train yourself to see things differently and choose your favorite topic...
Use the Skeleton 4-Quad. If you can play the game "Hot Seat!" - you can easily fill in these four sections regarding emotion to channel both voice and organization in one shot. Once four ideas are harnessed, choose one and write about that!
Never wonder 'what can I write about' again.
Step one: Select any topic or have someone give you one.
Step two: Write one sentence that represents the emotion symbolized by the icon in the box. (Rinse and repeat 3 more times.)
Step three: In each box, using the bullets, write three reasons you wrote what you wrote at the top of the box representing that emotion.
Step four: Choose your favorite one (usually the one you found the easiest to write - this is where your passion is!)
Step five: Get yourself a "Hey, Essay!" Rainbow Skeleton Writer's Block Breaker and write that essay - your outline is already complete!
