I lost my right leg and left lung to bone cancer by the age of 19. I had no choice but to develop grit just to survive. Then starting at age 32 I founded and ran a total of 9 tech startups and I sure needed the grit I had already developed to do that. Truth is, grit is needed whenever we take on something really difficult. In this podcast we will visit with people from those two very difficult pursuits as well as others. This podcast is full of advice on how to develop grit for whatever tough things you need to tackle including on how to tackle the great challenge of creating a new tech business out of thin air. My guests and I will convey our valuable startup experience via sometimes amusing stories, happily admitting our mistakes, but always helping the audience know the right way to build a successful startup that will be headed in the right direction the right way, maximizing its chances to become a profitable business. And you will be inspired when the guest is someone like Hugh Herr who lost both legs below the knees to frostbite while ice climbing. He has since gone on to be a world class climber but also the leading developer of bionic prosthetics in the world. There are hundreds of people as inspiring as Hugh.
