Hey y'all, here's Ollie's fanfic writing tip:
I have been where you are now. I dipped my toes into the world of fanfic, reading everything I could. I soon started to write it.
It was cringy. I still cringe. I've deleted most of those fanfics (I think some are still in my colournote app?). But they helped lay the foundation for my fanfics now.
I get compliments on my writing fairly often, and it feels good. I've been writing for years, and I'm learning more and more (from reading, writing, and Pinterest), and I'm happy where my writing is now. I'll still improve, but the practice has made all the difference.
Just keep writing. Even if you think it sucks. Learn from what you think sucks about it. Have fun. The rest will follow.
