From the decades it has been a  prominent question for all intellectuals that, "Intelligence" is a natural gift or it can be earn by putting gradual efforts? 

And off course, people seems to have a binary approach towards this issue. Some say few people come with brilliance in a particular area while other earn it by hard work and putting relentless efforts. 

Well, talking about my opinion. I have not come to a conclusion yet! Because I study many intellectual people some of them seems intellectual by birth and some of them seems to earn it by hard.
