I read the whole blog--through the meth, the raves, the enforced sojourn with your parents. I can honestly say I don't relate to any of that, and yet I read the blog to the end. Which means, you know how to write. I do relate to that. I love to write, and I do it as fluently as I speak. This doesn't mean my writing is good, it just means writing comes easily to me.
I agree with your premise--the more you write, the better your writing will be. Also, write with a consciousness of audience. I don't think you need my upvote--it's not worth anything, but I'll give it anyway. Nice, fluent writing.
