My first systematic foray into PD happened over Thanksgiving 2006. I stumbled onto the Early Riser article, which led to my reading all of Steve's articles. I've started adding other resources.
Prior to last month, I thought that the "self-help" or "personal development" industry was all about so-called "pundits" selling platitudes to people who were desperate to get help. But the quality information on this site, including the insights on this forum, have been eye-opening and inspiring to me. So, thanks everyone!
