I would say 0 advice and 100% PR.
The PR department who runs the blog thought would be cool to have some Richard Branson words there. So they sent up an email asking Mr. Branson to write a short advice post.
He started writing easy stories he use to share every other interview or lecture, and create a title to make his particular case sounds like a general advice.
The blog guy thinks it is still necessary to put a little more context to make it sound like cool, wise advice. So he writes an intro that resonate with founders. That's it. Out of the microwave advice to generate traffic.
For me, not a single word of value for my startup management. The HN upvotes tricked me. Just some curiosities about how Richard Branson do business.
