Hi Angela!
Good to hear from you! That's a tough question, though. Fiction's great, because it can sell to such a wide audience, but likewise, the competition's stiff, and you have to really hustle to be noticed. With non-fiction, people will usually come looking for you, because they're trying to solve a problem or have a shared interest. Once that person finds your book, it sells itself if it's well-written at all.
For someone like you, who has gathered information and life experience on particular subjects, that's a great place to start. You don't have to sell a million copies to be a success. As long as you reach the people you want to reach and touch some lives, you will be a success!
