Productivity.

The thing about getting things done, or getting any kind of progress at all, is that you can't wait until you have a better idea. You can only get a better idea after you've satisfied the first idea. So no matter how stupid or dead-ended your first idea may seem, get it out there if only so that you can move on past it.

We say, what's the point of the space program anymore when space travel is so unfeasible and there's not anything useful to learn out there? Well, the space program is what allowed the research which led to the technology that we have today. We laugh about how slow and huge and tiny-disked the computers were in the 70s, but without those first computers, and all the other slow, huge, tiny-disked computers in between, we wouldn't have the fast, small, huge-disked computers that we have now. (When I say tiny- and huge-disked, I am trying to talk about the amount of memory on the hard drives.)

But, I am actually talking about writing. I think about this huge gap in my script where I have to write who-knows how many scenes to fill it, and I think "I'll never get it done, I don't know what needs to happen, I just have this one stupid idea for one scene and that's not enough." Well of course it's not enough. But it's a start and you'll never get to the end if you don't start. So, I wrote that scene. Then I wrote another one related to it. And I ended up writing 5 or 6 more scenes all in the same session. And I was really glad I hadn't stunted myself by refusing to start because "it wasn't enough." Having something is better than having nothing, even if you think it's not enough. And having something usually leads to having more. Sometimes it takes a while, but it happens.
