Why Is Writing So Hard?

I mean, it's just words.

I use words all the time--well, some of the time, I don't like to talk that much.

But seriously, I know enough words. I don't know all the words but I know enough to write something.

Why when I sit down in front of my computer do I have an uncontrollable urge to get a glass a water, do the dishes, read CNN, eat an apple, have some chocolate, tidy the living room, change the laundry, open or close the windows to adjust the temperature?

I'm scared of writing.

What if I'm not good enough? What if I fail? What if people make fun of me?

Ugggghhh.
