Build strength through the combination of knowledge and experience - both are required to move up the value scale

Eben explains: 'a strength is really about expertise. Okay? So you're an expert, meaning knowledge wise, you know a lot about the topic, but you also have experience. When you add knowledge and experience and you put them together, this is where you go up the scale. The more knowledge you add and the more experience you have, the more valuable you become.'
