Amateurs obsess over tools, pros over mastery
It's a bit of a platitude, IMO.You can find plenty pros that obsess over tools. Like look at Adam Savage's Tested youtube channel, in which he makes videos surrounded by a vast mountain of tools, many of which he made or customized himself. Recently he geeked all over the fractal vise.The difference I'd say is that pros have a better understanding of what they need, don't expect tools to magically solve problems, and often customize or even make something from scratch.
