The best advice I’ve been given, and by a fellow author at that, is to just accept that not everyone will love your story. What’s more important is that you love what you’ve written and are satisfied with it once it’s finished.
That advice really helped whenever someone tells me my book pretty much sucks. But I take that and motivate myself to improve my writing on the next one. It’s not the end of the world if I don’t get 5 stars from every single person who reads my stories.
