All success?
> Where you are born, who your parents are, etc.
This is only true up to a certain point. Obviously if you were born in the ocean and your parents are dolphins, you're going to have a hard time starting and running a coal mine.
Every time I hear someone talking about the role luck has with success, they are usually giving examples of how bad luck makes success impossible.
Nobody here insisting that there is more to success than luck is trying to say something like "people in North Korea just need to tough it out". We're talking about the millions of people who have every opportunity to be successful, but don't do so, because they are unwilling to commit to what they perceive to be too risky, and too difficult. The attitude you and the parent stress is the attitude that keeps so many people lower than they should be.
Successful people usually are not successful on their first try either, how many times do they have to fail before you would attribute their success to their efforts and not that "well, 3,847th time is always a charm"?
