Imagine this setting:
You, a super-smart startup founder with a killer business idea, have a pitch meeting with an investor in Silicon Valley. You’re nervous. You can’t eat. You’re dwelling on all the terrible things that could happen in the meeting (forgetting key points of the presentation, fumbling over difficult multisyllabic words, falling out of your chair). The investor is willing to give your company funding, but only if you can convince him that not only your idea, but also your team and company can and will succeed.
