This is expertise - the quality of getting better results more often. It requires the ability to recognize generalities between problems that are different on the surface. An expert is more likely to get good results the first time he ever tries a specific problem, because he can apply generalized solutions to generalized problems! Someone without that abstract layer of knowledge is essentially solving the problem for the very first time. And while you can't get experience modeling every type of thing on Earth, you CAN apply expertise to any modeling problem you ever encounter. Which of course is the sentiment behind the saying:"Thinking rationally about [a problem] requires that you be able to discern [it's] most important aspects, know why they are important, and know what strategies will be most effective to ... maximize your outcome."
So what do you think? If you live as a specialist, do you ever expose yourself to other sets of problems in order to improve? Will you be specializing in your niche for the rest of your career? And if you're a generalist, do you feel limited (or unemployed) by a lack of significant experience in one field? Which do you think is the stronger path in the short term - when you need a job yesterday?"Jack of all trades, master of none; certainly better than a master of one."
