I kinda wish I did some creative writing practice before jumping into VN writing. I have a mechanical engineering degree and work in manufacturing. The only kind of writing experience I had at the time was technical writing. It gave me a lot of the strong fundamentals, but creative writing is an entirely different skill. I'm certainly not the best writer, I'll be the first to tell you that. But I've certainly learned a lot and gotten a lot better after working at it for 2 years (you should have seen my first draft ☠☠☠). I wish I had some of that experience beforehand. That said, it's not really a "regret". I'm happy I went for it and followed my passion. TBH, I wish I did it earlier!
