> Remember we used to spend enormous amount of time in school and in our spare time studying computer science? Algorithms, operating systems, compilers, and etc. All kinds of insights. All kinds of fun. All kinds of hard engineering. Yet, how much time do we really need to spend in our day-to-day work implementing or using the algorithms and etc that we have learned?

Because great insight and expertise stems from foundational knowledge.

I am a huge hockey fan. In the NHL, the players do not stop practicing the fundamentals once they make it to the NHL. They practice the fundamentals even more. Many practice the same drills as youth leagues -- stick handling, passing back and forth, shooting, edgework, shooting, rebound control, etc..

The best of the NHL might not hit the hardest, have the most accurate shot, or skate the fastest. What separates them from the rest of the lot is that they are fundamentally better than everyone else.
