I have a neuroscience background - that's what my doctorate is in - and I was trained to study hormones of attachment so I definitely feel my parenting is informed by that.
I'm not only a lawyer I have a post doctorate degree in federal tax law from William and Mary. I work in serious scholarship and work in the United States federal tax court. My husband and I raised five kids. We've raised 23 foster children. We've applied ourselves to education reform. We started a charter school for at-risk kids.
A writer should get as much education as possible but just going to school is not enough if it were all owners of doctorates would be inspired writers.
I think it's a mistake to treat different realms of knowledge as if they are some how fundamentally the same.
