Untrue
From the moment we are born we know absolutely nothing. It is only through teaching that we learn.
Our parents taught us to eat, walk, form sounds to form words. Our teachers taught us everything from reading to writing, mathematics, science, history and so much more.
We’ve learned about relationships from family, friends, bosses, coworkers, people we’ve dated and/or married, plus every other person that exists in our worlds.
I know I consider it a wasted day if I don’t learn at least one new thing, it doesn’t matter what it is.
Learning is a necessity, but also a desire for many of us. It’s what drives us to be better people, better storytellers and writers.
So, I believe that this statement is untrue, we can research and learn anything about any subject. In the end, it is up to us, but you can write about what’s familiar or what’s not, all it takes is the desire to learn.
