Write your own script
Image of being a screenwriter for a long-lasting series. At a certain point in the current season, the producers tell you that because of budget problems, you can no longer shoot on location, and they must let some actors go. When you receive the bad news, you've already drafted the new episodes following the plot agreed upon at the season's beginning.
What would you do?
You can whine against the producers, the industry or fate. It won't change anything, but it may give you some relief for a few minutes. But then? Walking away is an option; you can look for other projects in which you can express your talent. Or you can decide to stay and accept the creative challenge of reinventing the story within the new constraints. In the end, you are the screenwriter. You are the one deciding what will happen in the continuation of the story.
What if that long-lasting series is your career? Or your very own life?
Those are very particular cases in which you simultaneously are the screenwriter and the story's protagonist.
And, like in movie productions, things happen. Unexpected circumstances can disrupt your very well-planned script.
But, because you are the lead screenwriter of your life, whatever happens to your story, you can mend or even rewrite the script, taking in the new circumstances as part of the setting for your following chapters. Or, you can let someone or something else edit your script for you.
In any case, the choice is yours.
But I would argue that it's way more fulfilling to write your own script.
