How did you get into SEO?

I was already into computing, more the darker side though. My mum had a brand new website and the company who had designed and developed it quoted her a whopping £3k+ (as a basic starting fee) for the site, so she asked me if I could take a look into it.. From there, I met Todd Foster from FosterSEO in a gaming forum who became my mentor and one of my close friends.
