Staring blankly

There are days when I would sit in front of the computer staring at the empty screen wondering what to write. I would write something, then decided against it, write something else, decided against it and so on. This can go on for hours sometimes. At the end of the day, I will end up with nothing written. I cannot imagine how those writers can come up with interesting articles every day. To write just one paragraph is a struggle for me!
