I'm not there yet, not even in the nursing program but I'll share why it seems fitting for me.
For the most part, you can decide your schedule, not totally but you are not working five days a week all day long. I love staying home with my boys and plan to homeschool but I would also like to move into a nicer house one day so to work I go.
My spiritual gift is mercy. What better way to put that to use. Nothing says mercy better than showing compassion and caring for those who need it.
And lastly, like many others have said, job security. A good friend of mine was an RN before she even had kids, worked for a bit after her first was born then decided to be a stay-at-home-mom for five years. She made two phone calls and got a job just like that (it DID help quite a bit that she used to work there!) she had a job again. Fast forward about six months she is not house nurse in the ER. I know it won't always work like that but it does give me hope!
