I'm sure there are some lessons to be learned from Apple and Amazon and Gieco and BRKB and other glorious companies. But the number of lessons applicable to your company are less than zero. Because you are not Apple, you never will be.
And there is nothing wrong with that. We can hear what these companies are doing. We can see if there is any part of our culture, people, customers, products, vision, strategy, that are even remotely conducive to adapting Apple's beat practices. If not, we are way better off spending time developing our own unique obsession with customers, our own obsession with destroying product stupidity, our own obsession with a insanely focused culture, and so on and so forth.
For all of the reasons above I'm not a big fan of conference speakers or books that are entirely based on: "You should do x, y, z, a, b, c because those are exactly the reasons Facebook/Apple/Walmart are successful."
What works for them will not work for you. Find your own way. #harshrealities #beyoubecauseeveryoneelseistaken
