This resonates with me. A heuristic that often leads to success is learning the rules of our systems, both written and unwritten. Over-reliance on this heuristic shackles one to imagined limits. Many of the perceived "rules" can be broken.

As an example, many people assume you need to go to a top school to get a top job. But after several years working, that perceived boundary that so many are so hung up on seems like a joke to me.
