This is a really great observation. For many people they have been raised that it doesn't count unless you get the certificate. That has elements of truth to it in the job market, you need an independent third party to say that you have learned the material. However, for just as many people it has really about accelerating their ability to be effective by rapidly absorbing the knowledge and learning of people that have come before, which then allows them to push forward with that learning already in place. And that does change lives, and villages.
