Its a great job as long as its right for you (i guess like most) But if its not for you then it can be a very very hard job.
Most people who bleat on about the easy life teachers have are just jealous of the hols, as which any job you get the highs and lows.
The best bit of the job is working with the kids in the classroom; there is a lot of mince that gets tagged along.
Unfortunately there is an abnormally high divorce rate in teaching, and alcohol use is high and high early mortality rate in teaching. Anyone who tells you its not a stressful job really knows SFA.
Get into classroom and see how you get on a bit of work experience you might love it more than you think, or realise it’s just not for you. Try and find out before you fully commit to any course.
