Wow! There is so much truth in this! Write what you know, I have heard that so many times throughout my life and it always rings true.
At the same time it forces one to think more deeply on what they actually know and the real depth, or lack thereof, of their knowledge.
A great Philosopher once said the beginning of true knowledge is in knowing that we know nothing.

The real empowerment I gained from this wonderful post is a reminder to think deeply on where my knowledge falls short and realize the motivation necessary to learn more and keep learning.

Thank you for sharing this.
