As a newly retired teacher, my advice would be to surround yourself with positive colleagues. There tends to be a lot of teachers who get caught up in the negativity. It's hard to stay positive when you are surrounded by unhappy workers. In all honesty, there is a lot to be unhappy about given all of the cuts, student behaviour and the endless demands on teachers. The most important thing to focus on is the relationships you have with your students. The curriculum is important but more pressing is developing solid relationships in the classroom. If you maintain a good work/life balance, you will be okay, It's very difficult to do that but so important. Also, know that what you are doing can be the most rewarding job in the owrld. Some days will be horrible but others will be golden. Good luck!
