Congrats, I've self published twice. The 1st sold zero and the 2nd sold hundreds. The 1st was a Career Advice book and the 2nd was a niche book on Aerospace Quality Systems. The advice to go niche is sometimes wise. But I like my 1st book on Career Advice better. Everyone has a book in them, me? I think I might have 1 more. But man, the toll it takes on a person to write a book is huge.
