"If you do exactly what business schools teach you, you are almost certain to fail" - Clayton Christensen, HBS Prof.

This quote is very insightful, and I thought it was thought-provoking that a HBS Professor said this, but when you think about it it actually makes sense. Theory seldom works if applied blindly, but needs to be adapted to the situation at hand. Reflecting and disagreeing with theories often carries a lot of value as well.
