The difference is ALL doctors or orthodontists make a good living not just the 1% who pestered and annoyed all friends, family, and casual acquaintances to join their down line constantly. I hate getting a message or email from a friend I haven’t heard from for 10 years thinking they want to catch up on life and then within seconds the conversation turns to their latest snake oil product. It’s great to know that what you thought was an actual friendship is simply seen as a financial opportunity to a “friend” and if you don’t make them any money then they don’t have any time for you. If “not afraid of success” means not being afraid that the majority of your friends are now blocking your phone number then go for it.
