Film making & Production

Hi Aditya,
Becoming a writer is the easiest thing to do. You only need to write. Simple. However, what matters more is that you should be able to write well.
You may write a book in a month or two, or even sooner than this and subsequently, you would easily manage to rope in a plenty of publishers to take your work to its potential readers. But this would be, believe me, a perfect recipe of disaster.
One should write only when there is an interesting story to share, interesting enough for the hundreds of thousands of people to get excited about it. If the storys theme is not fascinating, at least the narration ought to be gripping and impressive. This process of conjuring up a story, giving it a blueprint, followed by giving a concrete shape to it and finally, critically reading the entire text yourself in a bid to improvise is arduous and painful. But this is the only way to rope in reputable publishers who can market your book well and earn you the respect among masses or probably in the writers fraternity at least.
One must remember that you read atleast 10 good books before you write your first book. And when you try your hand at writing, you must remember to elevate the level of your writing to be able to bring it closer to any of the 10 good (popular or award-winning or classic or all of these) books that you recently finished during your preparation of becoming a writer.
For becoming a director, you should pursue a course in cinematography to learn its basics and technicalities as it includes. You will then have your base on the film industry as you'the know what's the scope and where exactly to penetrate your talent at.
