Thinking on how to apply this kind of knowledge in business, I found this article about how the CEO and the founder of Evernote make decisions. A great example on how we can learn from other people mistakes and sometimes saving a lot of effort and a lot of money. In this case, the fear blocked him to invest in Uber few years ago, in a very early stage, and now Uber it’s a billion $ company.
Now he only decide based on the positive outcomes, and I totally agree, as a startup almost everything can go wrong, so you can’t take into consideration the negative ones, because if you do, probably the fear will block you right away.
