A question for other teen writers (or adults who were writing seriously as teens): are you currently seeking publication? (For adults: when you were a teen, did you seek publication?) Are you focusing on other things (life in general, learning the craft, anything) first?
I'm still writing my Big Projects, so it'll probably be a few years before I head off to the next stage of my "writing career". I'm really curious about people who have books ready right now.
I started writing seriously (as in, writing full-length YA novels, with the intent of pursuing publication) at the age of 13. However, I didn't actually query anything until I was... 19, I think? For a lot of reasons. One, my attention span was short. I would usually write a first draft, then get bored and move on to another one. I didn't revise much, if at all, mostly because I wrote by hand. *Sometimes* I would get around to typing it all up and revise as I went, but again, attention span. It was much more exciting to start a new book.
Also, since I wrote by hand, my manuscripts got passed around between my friends a lot. That served to stroke my ego to the point where I didn't really feel I needed to be published yet? I was so preoccupied with entertaining my friends (and sometimes total strangers at my school who would ask to borrow the MSS because their friend said it was good) that it was enough, for the time being.
Then I graduated, went to college for a bit, then started writing really seriously. I wrote the right book, saw a gap in the market, solidified my goals, and then started querying.
If I was a teen writer today, I'd probably make use of Wattpad. When I was a teen I used Fictionpress.com a little, mainly for short stories and vignettes, never for full novels, but if I was growing up now, Wattpad would be really attractive to me.
I'm not sure what approach I advocate. Maybe publish shorter stuff you don't care about, stuff with low risk for posting online and such, and meanwhile hone your skills on novels? When you write the right book, I think you'll know when it's time to start querying.
