Form vs Function- First principles thinking is a powerful way to help you break out of this herd mentality, think outside the box and innovate completely brand new solutions to familiar problems.


In layman's terms, first principles thinking is basically the practice of actively questioning every assumption you think you 'know' about a given problem or scenario - and then creating new knowledge and solutions from scratch.

Essentially, first principles thinking will help you develop a unique worldview to innovate and solve difficult problems in a way that nobody else can even fathom.
