I would assert that a recent graduate who wants to be an entrepreneur is mostly doing themselves a disservice by studying those things. It focuses your thoughts on how to run a business rather than how to solve a problem or turn an industry on its head. Sure, many of those things could come in handy in the future - but there are far more difficult things which you also have to learn "as you go".

As a service provider for small businesses, I see many amazing bootstrapped services & products come up around the world, that serves a very specific need for a small subset of customers.

I have a strong inclination towards finding many of them as a service provider because they just tend to be some of the best customers with great ROI.
