I'm currently a teacher and if it's definitely what you want to do then I tihnk you should go for it. It's very hard work, of course - you have to really *want* to do it. It's not something you should drift into because you're not sure what else to do. Also the PGCE course is pretty intensive, so you need to be prepared for that, and be able to take criticism well, because when you're learning to teach, you are going to get criticised. That said, teaching is an exciting, surprising and rewarding job, and if it's what you decide to do, best of luck!
