Relentless curiosity is a key skill

I recently came across Paul Graham's blog of essays.

"Knowledge grows fractally. From a distance its edges look smooth, but when you learn enough to get close to one, you'll notice it's full of gaps. These gaps will seem obvious; it will seem inexplicable that no one has tried x or wondered about y. In the best case, exploring such gaps yields whole new fractal buds." source

The following reminded me of something I call "relentless curiosity". When I'm asked what makes people successfully in the role of solution architect my answer has always been being relentlessly curious. Asking more questions to build an understanding since understanding is required to craft solutions.
