Ouch, that's tough. I used to have this motto to be untypical, but after a couple years I realized that's basically impossible. What I try to do now is not care whether the premise is typical or not, just to write it well, have good characterization, etc. And I often find that even when the majority of it seems like "nothing new under the sun," there are little bits and pieces of it that are entirely my own.
One example would be the oldest story idea I ever had, which I'm still planning on making into a novel. Basically, it's your typical heir to the throne story, where the main character finds out he's the king's son and goes through an adventure to claim his throne. But I've managed to come up with some original stuff such as the main character finding out he's the heir at the beginning rather than the end (as it usually is in these kinds of stories, if you've noticed), the "usurper" of the throne actually being the firstborn son of the king, and so forth.
Another example is my dragon rider story that I'm putting up here. Dragon rider stories are rather typical as well, but in my story I managed to come up with slight differences such as the main dragon being sarcastic and playful, and the rider going through disturbing physical changes such as scales growing on his skin.
But of course it's not always sunshine and roses. I was preparing the story I'm going to write for my March 31 deadline, when lo and behold! I saw I Am Legend over Christmas break
Okay, so a post-apocalyptic city under quarantine isn't so original after all.
I don't think it's necessary to "throw in the pen" if you're writing a "typical" story, as long as the idea really was yours to start with, and you feel strongly enough for your story. I think every author needs to be passionate about whatever story they might be writing, or the quality will suffer. You have to know that this story
needs to be told. As long as you have that, and as long as you don't start intentionally borrowing ideas from the movie, I think you should just keep on writing and not worry about it.
I hope my waffling has helped at least a little bit ^^'
You can find out things about the past that you never knew. And from what you've learned, you may see some things differently in the present. You're the one that changes. Not the past.

truth, that's your problem. I have no obligation to not offend you if I'm speaking the truth. The truth is
supposed to offend you; that's how you know you don't got it."
