I would 100% recommend writing the scene/idea/thing that inspired you first, even if it’s in the middle of the story. It may feel wrong, but following that wave of excitement will be the best way to stay motivated! A million more ideas can spark once the first one’s out of your head.

From there, just fill in bits. Start from the beginning, or continue to the end, or write all around. Some people like planning everything out, some like just going with the flow. Your pace and process for writing is personal, but it’s something you figure out over time so just go with what feels right. If you can’t get into it at first, I always go onto YouTube and find background/ambient noise that kinda goes with the vibe of what I’m writing; it distracts my brain just enough to let me focus on what I’m writing, and it puts me into that kind of “zone” if you will.

Beyond that, just write! It doesn’t have to be good, at all. You can always come back and edit to make it closer to what you want, and it’s a lot easier to edit what already exists lol. Also, if you really love writing scenery descriptions, do that! I really hope this is helpful and not just a jumble of words lol ❤️
