This is what I tell my writing students every semester about combating writer's block.
I once heard someone say... "Writer's block is not real. It is just you not wanting to write. It's your body telling your brain that you would rather do something else or you feeling too scared to say what is in your heart."
While I do believe that writer's block is real, so, I do not agree with that statement. But, the rest of the person said rings true.
This person's solution to writer's block, was to WRITE! I know that sounds crazy, but it is true.
Here is a method to combat writer's block.
First, go take a 5-10-minute break to take your mind off of the writing task. Go outside and get some fresh air or go to a different room.
Then, come back and grab a piece of paper and a pen (or marker or pencil) ... YES! paper and pen... do this by hand. This makes your brain, arms, hand, and fingers connect and work together.
Write the letters of the alphabet, write your name, write some random words (10-12), and finally write the poem "Hickory Dickory Dock." (No specific reason for this poem... just the first one that popped into my head. From my Pre-k days. LOL!)
Next, write sentences using the words you wrote previously.
After that, go read the assignment, writing instructions, or think about the writing task. Then, try freewriting or brainstorming on your topic or subject.
That should spark your creativity and writing inspiration. If that does not work, you are probably to stressed to work on the writing task at that time and may need to come back to it a day or two later if you have time.
That is why you should always start your writing task as early as possible.
