I just graduated from a good state university with a degree in exercise science. I am now in my first semester of nursing school. I chose nursing after exploring other health careers. I thought I wanted to be a physical therapist and I "liked it" but I didn't love it. I felt like nursing would be the best choice for me because I've never doubted my interest in health care and there is a lot of flexibility in the field. I've been in nursing school for about a month now, it's challenging but I've been doing well. After reading some of these threads and comments I'm starting to get really scared that if I make this career choice that I'll live a really miserable life. It seems that few are really happy. I honestly want a job where I'm intellectually challenged, feel fulfilled, and making someone's life a little better. Am I unrealistic about having this expectation for nursing?
