This might sound like "copying" but for the level editor things, as AGP said you can for example sit in a room, and that way works for me aswell. OR if it doesn't fit you, I recommend playing other stories that other people made, and you can learn new things, or get inspired by the story. I'm not saying to copypaste the things exactly, but to improve yours with them and modify them to your story in it's own way. Actually my "beginning" motivation to making a cs was by playing other custom stories, and I feel like I chose right when I started doing this.. Good way to spend a time, you become more creative as you progress
