Starting a blog (years after everybody else did it)

I've always been a late bloomer so it makes sense that it didn't cross my mind to start a blog until now. I was always a "writer" until about 7 years ago I guess.  I kept detailed journals of my life up until that point. I have boxes and boxes of journals from about the time I was 10 on. They chronicled my ski racing years, my crushes on boys, teen angst and mischief and college (or in my case post-college) drunkenness.  I don't know why I stopped then because my life has gotten so much more interesting since that day (when I moved to California).  I've grown up, gone through jobs, gotten married, bought a home and all those things you do after college. And I've realized that I'm missing out on keeping track of these things.  I know I'll probably never keep a journal again but I figure a blog is a way to keep track of the highlights. I don't know why I've decided to take this on now, at a time when I already feel like there's not enough time in my day to do everything I want.  I realize that the world is blogging is inundated by pointless chatter.  I watched a documentary on Fran Lebowitz last night and and I can't remember who she was talking about but she said something to the effect of "When _________ said people should write what they feel he didn't mean everybody." So I'm sure that I am a person she's pointing to with that comment, but at least I'm not trying to write books, right?
