We're all full of ideas for things, but as Twilight Zone creator Rod Serling reminds us, coming up with an idea is easy -- it's turning it into something is the hard part.
In an interview, Serling lays out his thoughts on writing, which are paraphrased in the headline above. Here's the whole idea:
Ideas come from the Earth. They come from every human experience that you've either witnessed or have heard about, translated into your brain in your own sense of dialogue, in your own language form. Ideas are born from what is smelled, heard, seen, experienced, felt, emotionalized. Ideas are probably in the air, like little tiny items of ozone. That's the easiest thing on earth, is to come up with an idea. The second thing is, the hardest thing on earth is to put it down.
It's a nice reminder that ideas aren't anything without execution.
