Businesses can be opaque. They are complex. You don't know how aircraft engines work either.
I advise other companies' CEOs, don't fall into the trap where you go, 'Where's the growth? Where's the growth?' Where's the growth?' They feel a tremendous pressure to grow. Well, sometimes you can't grow. Sometimes you don't want to grow. In certain businesses, growth means you either take on bad clients, excess risk, or too much leverage.
