Before you write, there are some things that you can do to move along the process. One great example is TAKE A BREAK FROM WRITING ALL TOGETHER! Our brains are like coffeepots and you need to brew your idea before you get a nice steaming cup of coffee. Imagine if you didn't let your coffee brew. You might be drinking what really looks like a cup of mud. Before you write, go for a walk, do a little dance in your living room, spin around in a chair, anything! Give your brain time to connect the dots and clear your mind of it all together.
I've seen people dislike writing so much that they carry it with them wherever they go! They call it procrastination, but it's really more like dread. Give your brain a break and think about other things and before you know it, you'll be making connections that you never thought of before. It's wonderful! It's like magic! It's like dropping off your dry-cleaning! That pickle stain is all of the sudden gone and you don't want to know how it happened! You just accept the fact that it's gone and then you act like it was never there in the first place!
Do all of these pickle analogies have you down? Try it. Go for a walk instead of sitting in front of a blank screen. Ride a bicycle. Take your friend's neglected shih tzu for a walk. Fly a kite. Make a cup of joe and drink it, too.
