Writing is an 'Art' and not a 'Science'. Therefore most of our English teachers don't end up as writers even though their grammar is excellent. The reason for this is that they work on the science of writing and not on the art of writing. If you focus on writing as a science, then it will be difficult to penetrate the hearts of the readers. If you win the heart, then you have won the mind because a large number of decisions are taken on the basis of feelings and not on thinking.
