It's become more fluid. When I was younger, I would sometimes take weeks to write just a couple of pages, but as I've aged, I've kind of had a hard rule that - on a day where I write - I am not allowed to knock off until I have at least six pages. They add up quickly!
Sure. I take both in stride. I mean, I like getting great reviews, but I'm also well aware that not every thing is for every person. Some people aren't going to like what I make, and that doesn't bother me.
I've never really had any trouble with it. However, I have had to do a lot of research on women's health and clothing. So... simply taking that kind of time is the most difficult thing, but it's worth it.
