Skipping Scenes

When writing, do you skip over chapters, write each scene in congruity or do you write each scene as they come to you and piece them together later?

Most movies don’t film scenes from beginning to end. Many of them begin at the end or somewhere in the middle.

When I first begin my story, I usually write a lot of scenes, then piece them together. But later I’ll try to write from the beginning, get stuck in the middle and skip over that, write the end, and go back.

How do you manage your scenes? What is the hardest part to write for you? Beginning, middle or end?

For me it’s the middle. I always seem to get stuck somewhere, and going to a new story is only a temporary cure.

Which brings me to my next topic. How many of you writers write more than one story at a time? I'm talking longer 50,000+ novellas and novels, not short stories. Do you ever get thoroughly into a novel and have a great idea for another one that you don't want to put off? That's where I'm at right now and so far it seems to work. After all, if I'm stuck on a scene in my first novel, I can work on my scenes in the next one, but will they ever get finished like this? Hmm...only time will tell, as long as I keep writing.
