I think it's worth reflecting on how he came into top football. He was Bobby Robsons interpreter at Porto, and apparently they hit it off and Robson valued Mourinho's input, and subsequently got him his first job as a coach. Just imagine that situation. You're an intelligent and fiercely ambitious outsider, and this world famous coach seeks your opinions and respects you. And one of the chief things you've got going for you is that you're not shaped by the dressing room community or by having been a top player for a decade, you're independent and see things from the outside. Things are visible to you that others miss, you can look at things differently, and doing so brings you incredible advancement. As you rise through the coaching ranks, you keep grappling with the problems that confronts every coach and every team, and you find innovative solutions to them, because the way your mind works is that you never ever go to other people for that, you do it yourself. And the results are amazing. You're famous, applauded.
And then you've been through it all, you stop looking for answers, and codify those you already have into seven principles. And you stop adapting. And you never forget that the reason you got there was that you always figured things out for yourself, followed your own head. No one handed anything to you. No one gave you the experience. You took nothing as you found it. You don't ask people, you tell them. And your job is to figure what's the right thing to do, and then tell people to do it. Only by now, you're no longer an inedependent-minded innovator, but a reclusive, ego-driven defender of your own orthodoxy in the form of those seven miserable principles.
