Then a bit about Harry Potter. I thought at first it is children’s literature, and paid no interest to read it. But my brother gave me the first book an advised me to try, and I went through the same, and it was then, as I read that, I came to know that, why the people running behind it. It was that much thrilling and I completed up to the fourth book and now reading ‘The order of the Phoenix’ the 5th of the series.
One more thing, which is essential to say that, ‘The Law of diminishing marginal utility’ does not work in this book. The Law of diminishing marginal utility states that, as a person increases consumption of a product there is a decline in the marginal utility that person derives from consuming each additional unit of that product. But in the case of Harry Potter Series, each of the books give more and more thrill and satisfaction.
