I'm probably not the only one who keeps wondering how people get ideas for their scripts. How do people come up with storylines that hopefully also make some sense?
Now, I can only speak for myself - and there's absolutely no guarantee that my ideas are great - but I think there are at least certain things that I get right.
One of the most important things that you can learn about coming up with ideas is that most of the time you don't come up with them, unless you write or talk about them first.
So, write or talk. It's almost never a bad idea to express your thoughts. If you're a writer, writing is almost always the right thing to do.
I mean, update your blog (if you have one), write on someone else's blog, comment on message boards or forums - as far as I see it, it's all good. As long as you write, you might get some ideas.
Talk to people about writing. Talk to your family, talk to your friends. Annoy them with your plans, tell them that you're going to do something soon (even when you aren't).
Do this because you never know what's going to happen - how one thing can lead to another. You tell someone that you're thinking of writing something.. and the next thing you know you're actually doing it.
Of course, getting started with your idea and your script only gets you so far. Just because you started doesn't mean that you have it figured out. Ideas aren't always good ideas.
When I start writing, I'll usually notice that my so called ideas won't automatically translate into decent storylines. Many times when I have an 'idea', it's just a scene or a couple of moments or something like that.
One way or the other I have to find a way to make it work. Maybe I have to rethink the whole thing and perhaps I have to make it about something else too. In any case I have to get more ideas.
But that's okay. As long as I'm writing, I'll keep getting ideas. As long as I keep getting ideas, there's a good chance that some of them are going to be pretty decent.
At some point, if you keep writing, those ideas turn into storylines and eventually those storylines turn into a finished script - based on your ideas.
