A healthier approach also means managing acceptable losses. That's different — and, ironically, much safer — than trying to prevent failures altogether, by over-relying on past data to try "managing" risks that are inherently unknowable. We need to see those losses not as failures but as investments in the future. To succeed, we have to make it cool to fail in the right places, as long as it's recoverable, and as long as we learn from the failures and adjust.
