There is no fear like the fear of a blank page. What now sits empty, could be filled with words. What sits empty, could also stay empty. There is no prerogative to bring words into the world, except for will.
You will the cursor to move forward, think of words, however imprecise, imperfect, and your brain tells your fingers to move and black type appears on the white background. If you don’t start, you will never start. These verbal utterances will never appear, and your words will never be read, because they do not exist.
If you think about it that way, you probably owe it to yourself to write something today.
