One of the things that make a person interesting to be around the stories that they tell. One of the best ways to have stories to tell is earning the things you talk about. When you earn a Black Belt you have a lot more stories to tell than if you just walked in and bought one.
If you won first place in a race you could tell someone all about the experience that you went through in training for it.
If everything is given to you and not earned, what kinds of stories can you tell other people?
