Write a book about my faith and beliefs

This is something that I have always wanted to try to do. I do not have a conventional spiritual practice, I would say that have none. But I do have spiritual beliefs and I think that writing, whether it truns out to be a book or not, would be a good way to flesh out my beliefs. Everything seems really abstract apart, but hopefully, through writing, I can bring it all together into a cohesive system of thought. Spirituality is very personal, so writing my beliefs would be worth it, because there is no other book I can read.
