My mom was an author and speaker while I was growing up. We traveled all over the country with her as she did seminars and sold her cook books.
Surprisingly, my mom barely ever sold any cook books to friends amd family. Almost universally, friends and family said they really wanted to read her books, but would never quite get around to actually purchasing a copy. You could always tell they felt guilty about it, but not enough to actually go buy the book.
As I've grown older, I've found the same to be true with almost any product you're selling- very few copies will actually be bought by the people you're closest to in your life.
And that's okay. Your friends and family are there for support. But don't make the mistake of thinking of friends and family as customers. Or they might just start treating you with the same distance as customers do.
