The other night I someone that I had written a book, and he replied, “What does someone your age know enough about to write a book?” He was joking, but I knew some part of him believed that to be a valid question.
His skepticism is fair, but in my mind, “being an expert,” “knowing enough” and “being qualified” are all irrelevant.
The question of whether or not you are an expert takes a backseat to whether or not your work is going to help people.
Critics will demand you have more expertise. Fans will appreciate the imperfections of your work and see the beauty in it.
When you answer to the critics, the best result is that they shut up. When you create with the fan in mind, the best result is that you produce something life-changing.
The choice is yours. Who do you want to please?
