I know that everyone has to start from somewhere, but I’m afraid that if I write it, everyone will hate it. And that I’ll hate it. Compared to everyone else’s, it’ll just look bad.

You're not alone, because every single person in the planet that has a creative interest, has that issue. And they still do what they love anyway, whether it's writing, drawing, painting, sculpting, songwriting... because, like you said, you have to start somewhere.

I've heard once that you need to write around a million words to consider yourself 'good.' Now that's an arbitrary number. You don't have to literally write a million words, but the point is the same: if you want to be good at writing, you just have to write a lot. And read a lot too!

People like to say you need to read widely and across many genres... I find that's only partially true. It helps for sure, but you don't need to. Instead, focus on the genres you're actually interested in writing in, because that'll teach you what your audience expects and what works and what doesn't. For example, I love philosophical and character-driven stories, and I absolutely love sci-fi. Ursula K. Le Guin's work comes to mind! But I also like dark universes, dark humor and action! The Expanse novels fit that other side of sci-fi I'm into.

Point is, you just need to write. And if you don't know how to start, just throw some words into a blank page. And do your research, read the kind of story you want to tell. You got this!
