I'm something of an 'on-off' LJ user. Sometimes I'll use it relentlessly for weeks on end, then go a year or so without it. So filling in a profile always seems a little obsolete in my eyes.
I like to write a lot. Whether it's reviews (I contribute to this site [username: Laba]), prose - short stories, random descriptive pieces, novels - poetic pieces or a random journal update I just love articulating myself. I adore finding new words to use. Vocabularly is a beautiful thing. Langauge is a tool and a gift which should not be squandered. Try it, you'll surprise yourself. I know I did.
