The difference between that and the step up is if you don't spend some time understanding why the cut-and-paste code worked and learning the how and why of things.

I've friends who are in the same boat and invariably the excuse is "I don't have the time to learn the theory, I have other things to do." Because of that, their workflow never really gets any easier. That's fine if coding is that side thing you do to make your job easier. That fails when it's what you want or need to do as an end to itself.

Also, I don't mean theory in the sense of the MIT "Introductions to Algorithms" book, I mean in the sense of the standard library, idioms, syntax and common usage of the languages and libraries you use.
