As mystifying as it sounds, zen is not something that can be easily achieved. One has to leave everything that he loves or hates behind in order to be free.
Well, all this righteous talk is alright, but consider this. There are far fewer successful people than unsuccessful ones. (Yes success is a subjective term, any reasonable definition will do for now though) After all that is why they are successful and everyone else is wanting to be like them. So, when a successful human decides to go into meditation it makes so much sense. He probably got fed-up (bored) of all his achievements and thought of exploring inner self. Wherever he will go, he will excel - even when practicing meditation. Spiritual intelligence will just come.
About the other guy, someone who is not wired as well as the successful fellow above doesn't even have the option to try that. Think about an average person deciding to explore spirituality. He can only be an average saint. Much below average actually - saints are not called learned people for no reason - their average is high. The point is that if someone has to struggle his way around, by deciding to quit in the name of zen, he is not fooling anyone.
And I didn't even touch what I started with - how much we are affected by our ecosystem, even when we are striving to be free.
