Should I start writing or plan everything first?
So, I have a light novel I've been conceptualizing for a while now (inspiring by manga). I wrote the basic idea two years ago, but only now have I returned to it to develop and refine it further. My question is whether it's worthwhile to start writing chapters before having everything planned and well-defined to avoid potential inconsistencies in the plot.
I've been writing as a hobby since I was 11 (I'm now 20+), and I've noticed this issue always holds me back. Although writing is a hobby, I also dream of publishing someday, which is why I'm here asking for advice.
Thank you in advance for your attention.
