He started by showing that just being good enough to do your job might work for your employer, but over the long run it's probably not in your best interest - financially or emotionally. He then went on to suggest a number of ways to build the skills that will help you to move your career in the direction you want. But then he went on to show how you can really build a name for yourself and become pre-eminent in your field. I have two other presentations to review before I go to bed tonight, so I'm not going to get into too much detail, but I will say that the book that the presentation is based around covers all of the material and a lot more and from a quick skim (hey, I only got it this afternoon and I've been busy having my mind blown at the presentations) it seems well worth $12.50 for a download or $25 for a paperback.
Really. Ask yourself this question. Did you present at InfoQ this year? If the answer is no, buy the book. You'll learn something worth much more than the cost of the publication! There's also a blog that seems worth following as well.
Oh, and don't blame him for the "Grunt to Guru" subtitle - that's all on me :-)
