A writer isn’t judged by how much he/she knows.
Think about it; there’s information everywhere. Search engines, gazillions of books, etc. and they all give access to a plethora of information. That’s why this time is called the information age. With technology, information grows exponentially. Which begs the question,
HOW MUCH CAN YOU POSSIBLY KNOW?
How many books can you possibly read? These days there’s even no time to read in comfort. We are always on the move in the hustle and bustle of life.
You can study many books, but ultimately, the best way to learn as a writer is to write. It’s that simply. Here’s the science;
Until you start to write (a short story, a book) you wouldn’t actually know what you’re looking for. There will be certain points in a story at which you’d need pieces of information that you couldn’t have foreseen in the plot.
You can and should plot in great detail, character profiling, setting, twists. But in writing a story, you’d need as much impromptu information as the one gathered in your plot.
What does this insinuate?
It insinuates that there is a certain pattern, a certain flux of information that only the actual process of writing can give you. No matter how voraciously you source for information, or how detailed your plot is, the actual writing brings its own sequence of knowledge.
Plot, brainstorm, as is the tradition of storytelling. But don’t overdo it. You will only waste your time and cause yourself more anxiety. Until you start writing that story, you will remain oblivious to certain things your brainstorming and plot can’t reveal.
