Went on a great SoHo walk with Tim Junio ending in the office of his new cybersecurity startup Ultra, For All Mankind and in their conference room is his product failure cabinet as a stark reminder of the hubris of many founders. Failures of once very successful products and brands like BlackBerry (of which I was a power user), Microsoft Zune, Snap Spectacles, and Blockbuster. Failure has many lessons to teach us, not only about when to adopt and innovate but also about when to persevere. One of the low points in my life was when my second book was rejected by 36 publishers. By rejection 25, you would have thought I might have said, “Hey, you know, there’s something wrong here. Maybe I should be looking at a different career.” Instead, I remember running out of money and walking, depressed, down St. James's Street in London and seeing a Barclays Bank. I walked in and, armed with nothing but a lot of chutzpah, I asked to speak to the manager and asked him for a loan. Even though I didn’t have any assets, the banker — whose name was Ian Bell — gave me a loan. It changed my life, because it meant I could keep things together for another, yes, 13 rejections! And then I got an acceptance. It makes the point that failure isn’t the opposite of success, but, as my mother often said, a stepping stone to success.
