Leo Zaccari asked: "What is the best way to describe your protagonist in 1st person POV?It always sounds forced and unnatural. What are some good ways to do it and make it sound natural?"

Excellent question. I think there are as many ways to do it as there are writers, and ultimately you will find your own way. I have accidentally stumbled on a couple tricks while writing my first book, and later I have seen other writers employing other tricks and stole those and tried them in my books as well.
