Hi Nadia,
as a nurse-midwife I can tell you, you don't have to attend home births if you are a midwife. I have only worked in hospitals so far (I'm not against home birth myself, that is just the jobs I have had so far). There's also birth centers as a happy medium. And, the training to become a midwife is much less than 7 years!
A few years ago I went through a period of wanting to define myself, like you... I also thought about getting a PhD/DSc. I researched it online and went to an orientation at a local university. I arranged specially for my kids to be taken care of all day while I was gone. It was a long day since I had to take the bus/subway to get there. I met with the instructors & asked a lot of enthusiastic questions. But I found at the end of that day, I had to laugh at myself, since I felt very satisfied and happy. I had had a day off just to think about me and be by myself, with grownups. It turned out that that was all I wanted, not a PhD. :001_smile:
