Entrepreneur

What have a physicist, an entrepreneur and an actor in common?

They all try to do something new and take the risk to be seen as a fool. Over the last few days I stumbled over three videos by a physicist, an entrepreneur and an actor, which at first have little in common, but they do. They all need to know when they are wrong in order to progress. If you are not wrong, then you are likely to be right, but that is often difficult to prove - often not at all.
