A blank piece of paper

"A blank piece of paper
is a formidable opponent,
but
you can defeat it. 
Just stare the thing down. 
Refuse to be intimidated. 
Take a deep breath
and
write a word
or two
on the paper. 
Make that a sentence,
a paragraph. 
Now you're in charge. 
Now you're writing."

~ Anne Mazer in Spilling Ink: A Young Writer's Handbook
