I don't want my kids to grow up with no father like I did. I came to the conclusion a while ago that you can work until midnight and not be finished or you can work until 6 or 7 and not be finished. I decided I'd rather work until 6 or 7.
I'm not obsessed by how I look or with being reed thin, but I do think that as a woman in my 50s, I have 40 years ahead. Looking after yourself goes hand in hand with looking good.
