Also, call your alumni association for the names of people in your field of interest. I know the idea may sound scary, but I've yet to coach someone who had a bad experience. Ask about whatever is most important to you while being respectful of your interviewee's privacy. Perhaps you can find a part-time position. Maybe you can just go to work with someone for several days and observe.
Internships are a great way to get a taste of what it's like.
And again, you can find out about internships from your professional association. Others, though, find a career only to realize that they need additional training or education. Many midlife women are concerned about spending years in school only to retire in another 15 years. My personal view is that every moment of your life is worth living to the fullest, and the prospect of spending 15 years in a fulfilling job is worth the investment in school. Her descriptions of menopause, relationships, fiftieth birthday parties, and bodily changes will resonate with any midlife woman reader.
