I am not talking about the tool per se. I am talking about the skill of persistence and creativity in the face of a problem. Learning a tool is useful, even invaluable, but if you don't have the persistence to use it, it's useless. And many tools are just partially useful under some conditions. So creativity in using them is also useful. So it's not about the tools, its about not giving up and trying different things, which makes all tools more effective, and problem-solving more likely.
