I just like to write. I've had a setting in mind that has sort of existed for over a decade, with much revision along the way (and more to come, probably). I study linguistics and am a few credit-hours away from a degree.
I've never been able to focus on any particular field or career or subject of learning. Instead, I learn about and dabble in practically everything. I have better than average to way better than average laymen's knowledge on dozens and dozens of topics, and I'm an expert in none of them.
I started writing when I was twelve and started worldbuilding around the same time. I don't read nearly as much as I should, but when I do, it tends to be sci-fi or fantasy romances. Four (I think) years ago, I started working on my main conlang, Zondulen, which now has 18 recorded grammar rules, with more that I've yet to write down, along with 2680 words. But besides Zondulen, I have five other conlangs that are mostly nothing more than phonological inventories, syllable structures, and writing systems.
