It is great hearing these highly successful people talking candidly about their experiences, both their successes and their failures. I love the quote about the oil company CEO who approached Randy Komisar asking about how to improve his companies innovation. Randy replies with something like "are you ok with failing 70% of the time?" to which the CEO looks at him like he is crazy. It seems like that is a crucial part of the shared experience of these people, get a good team together and don't be afraid to fail a bunch before something works out. These talks have definitely helped empower me to keep my eyes peeled for opportunities, and then when one recently presented itself, convinced me to go for it. It has also given me a realistic expectation that this specific opportunity probably won't turn into anything, but the networking, and experience I gain from it will at the very least not leave me empty handed.
Disclaimer: it is probably equally important to mention that most of these startups that people are talking about are created to solve some technical problem, so the startup teams are mostly people with technical backgrounds. I have a technical background and live in the bay area, which is a huge part of why I have any opportunities to go for in the first place. Most people who start these companies aren't people with MBAs, they are people with some kind of relevant technical expertise that they can contribute to solve some problem.
