tip: how to prepare to avoid writer's block
I didn't think I needed this until I tried but here is the way one teacher taught us to prepare for writing fiction:
1 - Settle your universe
Whether it is fantasy, sci-fi or slice of life, you must know your universe. Don't think about your universe as a setting but as some living thing your character(s) will interact with. The universe isn't only about scenery. It's about how society is shaped, what customs and holidays exist, if life is good or bad there, etc.
2 - Craft your characters
Once you're done with the universe, go to your characters. And I won't tell you to do a 10-page character sheet that will end up irrelevant while you'll write your story. I think you can start with 3 sections: who are they, what do they look like, what do they want and why. So it's basically part one being the basic info you can find on your own ID and part two is about appearance, tics/mannerisms and how they carry/express themselves. Part three is the most important one because it grasps the psychology of the character and you'll need to figure out two things: the character's goal in the story and the weakness that will become an obstacle to get to the said goal. For example, your OC wants to become an amazing singer (goal) but every time they get in front of an audience, they can't sing (weakness). It's only when they will break free from this that they'll get closer to their goal.
3 - Tie your knots
Once you have your universe and your character(s), you can settle your plot points. Only break down the events that will affect all characters and/or the universe. That way you can focus on "main" scenes and work through them as freely as possible. I realised that breaking every scene restrained and burned me out. But if I settle 6-8 plot points, I still have a direction and I'm free to write as I go. It's a good compromise for plotters & pansters.
I don't know if this 3-stage prep will work for you but it did to me. I wasn't hit by writer's block and wrote 57 pages in less than a week.
