Skill of your too directly impacts your ability to complete a task. If you struggle to prep food for cooking, you're going to be slower and probably less effective than the master chef who doesn't even have to think about how to dice.

But I'll agree with you in this way - there are a lot of people who want to just get good at their tools (huge vimrc that's mostly unused) and don't care about how well they actually write code. I think it stems from procrastinating.
