Sure, go for it. Writing a book takes a long time; I've been working for a year (minus five days), and am only to chapter seven so far. Given that, you'll doubtless have more material to draw from as you get older and write more. I find writing to be a greatly rewarding hobby, and would encourage it in anyone even remotely interested. You don't have to be perfect at it starting out; the more you do it the better you get. I've had to go through the short stories I've been accumulating since I was sixteen (whose word-count now totals over that of six and a half novels; yes I counted) and have had to do some serious punctuation and paragraph structure overhauling at least three times so far as I learned more about the structural rules for writing. Regardless of whether or not you wind up publishing, I would recommend giving a novel a go, and then letting us here on WP read the draft
