Mark Zuckerberg's studies in college, prior to Facebook, included Computer Science and Psychology. Marissa Mayer, CEO of Yahoo similarly studied Computer Science and Symbolic Systems (a hybrid computer science and psychology program at Stanford that emphasizes cognitive science). Reid Hoffman, CEO of LinkedIn, also studied Symbolic Systems and Cognitive Science. Computer science degrees and programming skill might get you a job at Facebook, Yahoo, or LinkedIn, but that's not enough to create Facebook, Yahoo, or LinkedIn. (No amount of degrees will allow you to perform such a feat.) They didn't just study computer science, they branched out into psychology-related studies that now directly apply to how their businesses capture the eyes and ears of consumers. In looking at these tech moguls we discover a principle: unique sets of knowledge (combinations of different fields and interests) put you in a position to do innovative things later on.
The best example is that Steve Jobs attended Reed College for a short period of time and at one point took a class on calligraphy. The class was not and still would not be very practical or useful in your career unless you become an illustrator or lettering artist. Jobs still decided to take the course and enjoyed every minute of it.
Years later, while creating the original 1984 Macintosh computer, Steve Jobs was able to connect the dots between all of the computer related knowledge he had and that calligraphy course, and introduced the first computer that could use different fonts in that 1984 machine. It's not that Steve knew that the calligraphy course would be important later on, but that he was willing to take the class and develop a unique set of knowledge that allowed him to innovate in a special way after the fact.
The institution will not graduate with you with a unique knowledge set on it's own: you must develop it by reading, learning, being mentored, and exposing yourself to all sorts of new and exciting information. Once you get past the standard fare of education (reading, writing, basic sciences and history), expand your reach into every other subject that you can get your hands on and learn to apply it to what you're doing.
Just in case learning is not always wrong when you view it in this light. The just in case learning that you do in school is just wrong considering the fact that everyone else is learning the exact same material; just in case. When you learn for your own purposes, learn everything you can just in case it comes in handy later: just get out of the comfort zone of learning what everyone else is already learning.
