I have to entertain, because if I don't entertain you, you're not going to continue reading. But if I'm not out to enlighten, or change your mind about something, or change your behavior, then I really don't want to take the journey.
I would get up at 3 in the morning and write. Or sometimes I would write at midnight. Or I would write when my child napped. It wasn't a burden. I was so enthused about what I was doing at the time that I really didn't mind.
