My daughter used to pick a key word or phrase she felt related to her topic, then she would free associate with that, not sentences, just a blank piece of paper and pencil and write whatever words or phrases come to mind. Even if she didn't use them in the long run, it was able to create the creative shift required to set the days' issues aside and let her story fill her mind instead.

That's just a suggestion though. So feel free to join us here any time.

Some times, it just isn't right. Stop beating yourself up because you aren't in the mood.

Maybe you were missing your wife?

I think there is something nagging you till you get it done, and you need to get it done - paint the bathroom, the dog needs a bath... something?

Either a guilty conscience or you're afraid of failing.

Maybe if you had to wear a cast for a while and HAD to sit since there's nothing else you're able to do, your mind will be free to wonder wherever it may.

Anyway, good luck . .

Just kidding!

that might be your problem...

not kidding

am kidding..

That's what usually stops me from getting back to it. There are so many other things that are easier to do at that moment.

I obsess over commas, semicolons, characters' speech patterns, EVERYTHING!!!

Your inner editor is shouting too loudly. You need to make her take a step back. I find that writing longhand (especially if your handwriting is lousy) quells that editorial voice. Something about seeing my words on a screen makes me want to perfect each sentence over and over again.

What do you enjoy writing about?
