The same can be said for writing, in fact, which begs the question: At what age did you start writing? If you would rather not say, then how many years have you been writing for?
TL;DR I've been writing since 13-14 and finally have a solid story that makes sense now that I'm 23.
In all seriousness, if I count my crappy fanfiction, since I was 12. That was when I started posting stuff online anyway. On & off throughout my teen years for both fanfiction and original stuff. Though, looking back, I wouldn't count anything I wrote pre-uni as decently executed.
I would consider myself to have first started writing a proper story at 13, when I began a fantasy novel. I had ideas for a huge interconnected world, maps, languages, magic systems, all that. It lasted maybe two years, with about 30k words total, before I realized it was pretty terrible and moved on. I continued on in that vein for some time, writing between 10 and 20k a year, until I discovered nanowrimo in my early 20s. I think 23 is when I'd consider myself to have gotten serious about writing. I had known I loved doing it for a long time by then, but never had the fortitude to keep going once I got past the early burst of inspiration. Nanowrimo changed that, and taught me how to push on even when I got past the honeymoon phase of a story.
And then maybe five years ago I started posting online. Fanfiction at first, then more recently I started posting here. Since joining RR, I've managed to stick with a single project for an entire year, which blows my previous record out of the water by about 8 months. :) I love being able to get real-time feedback from readers as I go, and the accountability of knowing there are people out there who actually want to read the next chapter helps keep me from giving up. I love it. :D
Now, if only I could figure out some way to make my writing profitable, then life would be practically perfect...
But, no, in actuality, it was around my days in college.
I wrote and I wrote and I wrote. I read and read and read.
From time to time I felt like, "Now is the time to think about publishing", but I never reached a comfort level with it. I was happy enough just writing, but now I've reached a point where I'd like my works to be read.
Before that, I did what was probably microfictions in elementary school and I remember my teacher asking me once if I had finished my story yet since the period was about to end. I told her something like "not yet, I'm still writing the opening scene." Around the same grades we had these tablet things and we were supposed to do some animated comics on them and mine took forever to finish... don't think I ever did though. All I remember is it had an ungodly amount of frames.
When I was 10 years old or younger my brother and I did some comics. I think I gave him ideas and he drew them, he was maybe 5-6 years old or so.
I do remember when I was ~13-14 years old I told my English teacher that I couldn't do this writing project at all because I had literally nothing to write about.
After the country RP stuff, I took a break from writing anything resembling a story because of writer's block and depression I had at the time. Though I did take elements from the country RP lore stuff and used it as a basis for research notes for a new story which was the earliest basis of my novel.
After I turned 24 last year I started writing my ideas into a story but I ended up scrapping most of it and going in a different direction instead. Looking back on it, even on its second draft it resembled more of background lore than a real story so realistically I didn't start writing until about 6 months ago when I had to soft reboot my story since the second draft version was complete trash.
Thank you for coming to my Ted talk.
