I think this is spot on. I agree with many of the things in the article. Especially the part about setting quantifiable goals. Too many times I find myself not doing this and getting "lost" in the process of learning and then kinda giving up from being overwhelmed.
I totally agree, but what really sets this apart is not only the quantifiable goals. The key, in my opinion, is to have a practical goal. If your goal is to learn C# and be able to write it fluently, then that is kind of quantifiable. But if you set out to learn C# to program a specific game/applikation etc. then in my opinion, you would learn much more along the way.
I attribute that more to having direction. Sometimes when learning things one simply meanders through a field, absorbing knowledge as they find it, and figuring out how to use it.
When you have a concrete goal (I want X to happen), you can (usually!) figure out what you need to learn in order to make X happen.
