Looking back 10 years ago: how much can we change?

It turns out that I had a Wordpress blog that I used to update very frequently when I was in school, then I stopped blogging and later moved my blog to another CMS. 

I've been trying to recover my very old blog content and I just found a way to get it back: the old, good web.archive.org.

Browsing this archive I'm wondering: who am I? 

I mean, it's very interesting that did write that much.  But it's also intersting that I kind of like the way I wrote those posts and yet I know that I said some childish things — not that I regret a single word.

How much can we change in a year? In five years? In 10 years?
