Pattern recognition is one of the reasons I was so successful in life - my ideals of success, not everyone else's. I often see patterns that others don't notice and this gives me advantages over others in many areas. Where you see a pattern you can preempt if not predict what's going to happen next.
It's the most important tool for any predator, why waste all that energy chasing your food if you can just sit and wait where you know it's going to be. I think it also ties in with the way we see faces and living shapes in many inanimate objects, a part of our mind using known patterns to try and filter out camouflage, the ability to spot hidden prey and other predators. This all happens subconsciously of course, it's not something we think about, it's just what our brain does by itself.
