What you just described sounds like inexperienced writing… In which case the arc will be either ill-defined/confusing or be clear but boring. When writing, I think we want to hit a spot where we are comfortable letting the story take its pace, and or are really good at outlining and planning everything out. Some people are really good at that, but it’s something that I think takes practice to do well, and is probably something one does more when they are writing books, and even more books.
I think the more books I write, the more value I will find in outlining.
