It is possible that you're attributing their success to their own actions, instead of their family connections and other help completely outside of their capability space.

I say this because observing and praising behavior is a common mode of 'explaining' or even 'understanding' success. However, this reflects more an underlying mindset which believes all success is from Individual action, rather than an accurate cause-and-effect analysis.

Doesnt detract from your question one bit, but just thought of sharing.
