What's your ff.net name?

I will try to put it to good use now.

(I would have earlier, but then I got distracted with making an AMV for four hours. Windows Movie Maker, thou art a cruel mistress. At least I got it uploaded with only a few minor timing problems. That is considered an accomplishment when you have Windows anything.)

Again, thankies! *gives you all cookies*

I fall victim of that quite easily (that's why I tend to take a looong time writing missions)

The best thing I can tell you (as it works for me) is to concentrate on the one you are still writing with no troubles and leave the first mission aside. Then, when you feel you truly want to start working on the mission again, re-read what you have written, do some corrections if you find something that sounds off, and don't be afraid to rewrite half of it.

For me, it works. I hope it helps you...

You could just try writing any little thing that comes to mind until you get the flow going again.

Although, if it's for specific stories and not just in general, I would try going with the other suggestions here.

Sometimes when I get writers block I just start over. Like Phobos said, it's sometimes that a character has done something that doesn't fit, and if that happened at the very beginning, well, there sometimes isn't anything you can do to fix it. I'd like to emphasize that this is only on shorter stuff that I've done this, ie, everything I've ever written.

I'd also like to mention that one time, when I wrote myself into a corner in one of my missions (my agents got Sued,) and I was about to start over, I suddenly got a brilliant idea. Namely, I asked Caddy if he wanted to collab with me, and his agents swooped in and saved mine. Sometimes a sudden dramatic event can get a story going again. Dunno if that's relevant.

...that writers block is a sign that you have taken a wrong turn in your writing. They would suggest going back and reading over what you have to try and find out where you went wrong. Sometimes it is a small thing (a character reacts in a way that doesn't fit), but it can be a big thing (the main character goes to the warehouse, instead of the bank where he would meet character x).

So, take some time to let the writing sit. Go do something else for a bit. Then come back and go over what you have.
