I'm not saying you're bad at programming, I'm saying you're blaming the tools for your lack of discipline. Plenty of good programmers I know are undisciplined. But you can learn, and it's not the tools' fault that you didn't do so before. Hell, I'm a VS2010/Eclipse driver but I write MSBuild scripts by hand and I spent time the other day debugging the make/ant monstrosity. Limiting yourself because it's the only way to make yourself learn what you need to learn may work, but why not just learn it?

(And re: Eclipse--yeah, it's a bit of a hog, but hardware is cheap. Developer time isn't. And the features it provides have no equivalent in vim et al.--just look in the Source dropdown menu for a number of significant productivity enhancers. Those are some of the more minor ones, even; Open Type probably saves me half an hour a day in the monster of a codebase I have to work in. Eclipse is by no means perfect, but it's geared toward reducing boilerplate and stepping on the annoyances involved in Getting Things Done.)
