the only interesting part is reading about the humble beginnings, the dedication and belief.
what would actually be useful to read about is failings, where OP failed in transition to manager and how he overcame those failings. I mean there's a paragraph in there but it's so boring -- "I read these 3 books". ok there's a little more meat than that but it's too nonspecific to be interesting.
come on people, let's not just throw love out there for no reason. it has to be earned. this article doesn't earn it.
OP should read _the hard thing about hard things_. there are many anti-lessons there, don't treat it as gospel. but read it as a guide as how to write something that actually delivers a lesson.
i await your downvotes ... :P
