I'd also like to add that there is nothing wrong about opting for a shift to a different career track, as even with having collected sufficient information beforehand, you can still end up acquiring a different perspective on a choice initially made. I myself could have opted for a teacher training curriculum in the first place, but at the time, I couldn't quite see myself in this job. So far, I but have not regretted my decision to acquire a teaching degree on top of my M.A. - demanding as teaching can be, as I keep finding out in my side job. Which, tellingly, does give me a lot more in the way of insight than most uni courses have done, but that's a different story.
