It could be something like, “I thought XYZ was easy and ABC was hard, but–”
Or it could be something where you thought you HAD to do something one way (organize, use a certain program, write in a certain POV, etc), but you ended up handling it in a fashion that was different once you became experienced enough to see things differently.
What preconception was dashed as you grew in experience and skill?
That’s nice that you know where you are in your journey now.
I also feel no regret for the eschewing outlines as long as I did(actually up until today, I feel differently about them but haven’t taken the plunge yet), it’s been working for me fine.
But it’ll be at least interesting to pivot and try out an outline to see how that affects longer stories that I want to be more cohesive.
