All good points. It's not just the money to be fair. I know teachers whinge, but it's emotionally draining and I don't know how much more I can take. And you can't actually do much with your holidays... You're not paid enough. I keep myself entertained, but you're just off work, not really on holiday. And yes, I work a huge amount of hours. Then you turn up and the same mentally unstable kid needs restraining again (yes, it is like that) and all you want to do is quit.
Anyhow, thanks for the advice. I need to balance everything and think about how long it will take to build a business again.
