What is success of failure of education closely tied to

I think the best answer I have for you would be this;

Just because you are educated, it does not mean you are successful. Quite the opposite actually.  One who knows how to read a doesn't read, is just as successful as one who cannot read.  The smarter you become, the more you begin to realize that, there is always more to learn.  Always be humble and teachable.
