Good for you for walking away. I started out in my professional career wanting to be a teacher, but when I finally found a teaching position, 18 months after graduation, I only lasted 5 months. The kids were horrible. I might have had an easier time had I started calling parents from the first time someone disrupted my class, but I was afraid if I did, it would look like I couldn't handle my students. I ended up getting fired from that job after just 5 months, the day before my 25th birthday, and never went back to teaching in a "traditional" classroom, although I try to teach through a lot of the writing I do.
