I am a 35-year-old mom of four, ages 4-9. My dream has always been to be a doctor. I have some college credits and have been working as a medical transcriptionist for several years. I would love to hear from others who got late starts in their careers and/or did it with a big family. Does anyone think I can still realistically go for it? I see so many obstacles, but I do want it soooo much!
