Well intentioned list, and generally peppered with survivor (or failure) bias when trying to consume these bullet points without the context of the contributor.

The best across-the-board advice that I've heard from others:

  - Own it. Be the best operator for everything in your business.
  - Scale last. Very few companies have failed because they couldn't scale the business (but did everything else right).
  - Keep at it. Blood, sweat and tears.

Even at that, the mentors who I've had in the past said take these things with a grain of salt.
