Not really an advice, but just a phrase: “Can you show me something you have done?”. My brother was introducing me as a developer for a project he was responsible and the supervisor wanted to meet me first. I was prattling about all the stuff I know about and I was real proud about it. He interrupt me with this. That’s when I realise all the things you know don’t really matter to people if you can’t actually solve their problems and they aren’t confident that you can. I switched my methods after that. And instead of pursuing knowledge for its own sake, I make sure, I actually practice and build thibgs instead of just be satisfied with “I know this”. 2 years later, I started making money on gigs and contracts as a programmer.
