"The metaphor I routinely use is polar bears in the Sahara desert. You take creatures adapted to the cold and put them in the heat, the very traits that allow them to survive in one environment will conspire against them in the other. We are polar bears in the Sahara with one important distinction: we are smarter than the average bear. Once we identify the nature of the problem, we can think our way out of it. But it begins by acknowledging you didn't fail because you couldn't succeed. Because you didn't even know what the scope of the problem was. It's not your fault."
