Writer's block - fact or fiction?

The short answer: Fiction.

The long answer: I don't believe in writer's block. I am a writer myself, and I have battled what all the other writers call by that name. However, I call it by a very different name:
Laziness.

I know it's shocking, but it's true: Your book, story, poem, or whatever will not write itself. Yes, sit down. It is a large truth to absorb. I struggled (and still struggle) with it.
If you only write when inspiration strikes, it will take you weeks... months... years to write what you set out to write. Sitting down to write is one of the hardest things I know of... and not eating the last cookie, but that's off topic.
It requires determination, hard work, and perseverance. Even when you don't feel like writing, you have to push through. One thing I tried, and found works well, is to write five-hundred words a day, even when you don't think you can. Believe me, when you just write, without looking back at what you just wrote, those words will fly by. I am a hen-pecker on the keyboard, and yet I did it in less than an hour. Is 45 minutes of your day too much to ask?

Food for thought. Please let me know if it helped. :)
