Writing isn't easy

I wrote this 100-words exercise earlier this week:

Sometimes I sit in front of my computer for quite a while before I think of something to write in this little white box. I don't know why it's so hard sometimes to pull words from my mind, draw them through my fingertips, and, like magic, it seems, make them appear on the screen. But as Anne Lamott and countless other writers have said (or written), writing is sometimes a struggle, and no matter how successful a person is, there will be days when writing a page, a paragraph, even a sentence is all that he or she can manage.
