Holding Ideas Back?

I know I keep promising to talk more about ereaders, and really I will! But I found something interesting that I must talk about right now! (Isn’t that always the way with me?)

Here’s an idea proposed by Benjamin Percy.

And here’s the question: When you write a story, do you put every good idea that you think of into the story, or do you hold some back for the next story–just in case?

Personally, I blab it all onto the page. In one of my WIPs I had all these different plot ideas that were related and I couldn’t decide which one should go in. So… all three went in. She grapples with all three ‘issues’ which actually works nicely, I think. And it also puts me through my paces–I love a challenge! I’ve never thought of holding tidbits back to be used in other stories. If anything, I have to pull things out as I can sometimes try to squeeze too much in! Although, by putting too much in, I find that I have choice. Which detail idea was the best? Which one says the most about the character? Which one is unique and memorable?

So, I am curious… do you put it all in?
