Today we discuss the laborious, painful processes that make and break competitive advantages. To illustrate this concept, this episode is going to feature: Paul Graham (of Y Combinator), Mike Posner (a prolific singer, songwriter, rapper, poet, and record producer who received a Grammy nomination for song of the year), Gary Gulman (a stand-up comedian), Charlie Munger (a legendary investor), the Green Berets, and the New England Patriots.

And as a bonus, we'll explore how Marcelo Garcia provides an example of when to break the principle—and why.
