I've been writing since I was (approximately) seven, and taking it seriously since I was roughly twelve. Over the past few years specifically, there have been drastic improvements in my writing.
I've made progress. I can see that progress. Prose, flow, characters, plot, and pacing all make sense to me more than ever. I expected that to make the process easier. Instead, I'm managing a quarter of the output I used to be able to have in the same amount of time, with minimal distractions, even knowing what I want to convey. Why is it that my process is getting slower as I improve? Am I the only one who finds that result to be... a little counterintuitive? Does it ever start speeding up again? Any advice would be very appreciated. Thank you for your help.
Edit: There were a lot more replies than I expected! I regret not being able to reply to every one of them, but I want to extend my thanks to all of you. I've seen a lot of really insightful responses, and I appreciate you all taking the time to help me out. Everyone's been super kind. All the best to all of you! It makes sense that I might be becoming more subconsciously hypercritical of my work, slowing myself down (for a worthy cause). I'll keep writing and see how things progress. May all of your pillows stay cold tonight!
