When I took my first actual SEO job I was already aware of who Matt Cutts the Google employee was, but as I grew in the industry I became aware of how kind, honest, and insightful of a man he is. We've never met in person, I wasn't around in the heydays of SEO for dances and the like, and I've only seen him talk once. That doesn't mean I didn't learn anything from him, I highly doubt I'd be where I am today without his videos, blog posts, and tweets. Not just as an SEO, but as a person. Matt's 30 day challenges have inspired me for years to work harder to be a better man and to pass that along to my staff and students when I give guest lectures.
