Let me start this off by saying that I can't even begin to remember what I wanted to say about this topic. I know this title was supposed to guide me somewhere, to the right ideas, but it just isn't. Maybe I'll come up with it later, but for now, this is what you get. (And just in case you don't know, a "spec script" is a script you write for no guaranteed pay. You hope to sell it some day. "Spec" is short for speculative.)
Come to think of it, maybe that's what's important. Your life is essentially one big spec script. How well you live it may just determine how well you can sell it.
Because, if you haven't heard it already, we should be trying to live good stories. If we try to become the protagonists in our own lives, we might find change come about where we never expected it. Good characters want something and are willing to overcome any obstacle to get to it. The same should be for you.
So that's one tie-in between lives and spec scripts, but that's not the one I wanted to make. I know that for sure, but I just can't remember the one I was aiming for.
In the meantime, how about this? Writing a spec script, like I said before, is for no guaranteed pay. The only reason to write one is because you love writing so much that you have to do it. When you know that only one in a thousand scripts sell, you only do it if you know you can't not do it.
Maybe we can all live the same way. Let's live life like we'll never have money, because maybe we'll just never sell. Let's live life because we want to. Because it's wild and it's scary and we're characters who are ready to face our dark nights of the soul so we can come out on the other side the people we were already meant to be.
