I agree with absolutely every point on that list, and I definitely wish I had read something like that when I was starting out.

The only thing I would add: Be curious. Eliminate as many magical black boxes from your day-to-day work as you can. To some extent, yes, you should be playing around and experimenting. But some of my most rewarding self-taught lessons are from diving into areas that I took for granted (how a web server works, jQuery and Django's core, protocols, etc) and exploring until I felt like I had a good grasp on what was happening. Those monstrosity config files for things like Apache and PHP? Delete them. Now watch them fail. Learn what the default are, the bare minimum that you need to get it up and running, and expand on it. Find the areas you're uncomfortable with, and beat the living hell out of them.
