I've recently decided to get a 'real job' and do instructing occasionally, weekends only. It's a huge relief. Maybe that way I can afford the IR without horrendous debt.
If I could realistically carry on like this, I might. But I'm happy to swan out, knowing that they're all desperate and I could swan right back in again any time I fancied it. If I was offered a decent wage and some security, I'd jump at it and even self-fund further training as a career instructor, but right now? Sorry, but what's in it for me?
