What should I write next?

I'm a poor college student who spends most of his time working and studying. My creative output has been suffering. Over Thanksgiving break, I finally found some time to write a short story. I wrote one that I'm happy with and one that I am not. I've also been reading a lot lately, and it's inspired me to write again. I have a few ideas that I'm excited about, and I want to make sure that I get the most out of my time. I want to write the most engaging thing that I can while I have some time to focus on it.<br><br>Here are the ideas I have so far:<br><br>1. A sci-fi retelling of the Iliad with a few changes to the original story. <br>2. An expansion of the world I built in my short story that I'm happy with. <br>3. An expansion of the world I built in the short story that I'm not happy with. <br>4. A science fiction take on the Guy Fawkes Gunpowder Plot. <br><br>What do you think I should write next? Do any of these ideas stand out to you, or do you have a different idea that you think I should run with? Any feedback is greatly appreciated, and thank you for taking the time to read this.
