I have tons of story ideas

Question: I have a lot of ideas that I want to expand into different stories. But I have this one huge thing that I want to do most of all. Whenever I have an opportunity to write for something, I don't ever use any of my ideas because I want to "save" them so (if I get published) I can write all those books. I know this is a stupid question, but do you have any suggestions? With so much going on in my head, I don't get anything done.

Answer: You're never going to run out of ideas, unless of course you get in the habit of ignoring them and putting them aside to use later. In that case, your subconscious may get tired of rejection and stop giving you so many ideas. (Don't let this happen!)

You're also not going to get published if you don't turn your ideas into stories and novels. Don't hold them back. Put your best ideas into words. Practice writing. Polish your work through several drafts. Getting published is tough. To give yourself the best chance, submit your best work.

I don't know what you mean by "an opportunity to write for something." Perhaps an assignment for a course or a journal? If so, go ahead and use your ideas. You don't need to give up ownership of your idea. Many published short stories have been later expanded into novels by their authors. If anything, the novels are more successful because people who liked the short story are more likely to buy the novel. Use every opportunity to practice writing.

Just pick the one idea that seems to be nagging to be written right now and get started. While you're doing that, make sure you write down as much about your other ideas as you can, so you can use them later.
