Quarter life crisis.....if i live to 112 that is

Ages since i've been in here! Too long! I started my Postgrad diploma in Primary Education and after a truly awful placement my whole teaching life has been thrown slightly off balance. Just kind of fed up of the Scottish education system to be honest - what kind of difference can I really make when i'm spread among 28 kids?? Not to mention the hours.....spending my spare time prepping for lessons is no problem at all (dare i say it can be quite fun) but spending longer prepping than actually teaching?! Daft! Definitely feel like I need a change of scenery. I think I was maybe a bit too chicken to really do this, but i'm not getting any younger (unless someone has actually fashioned a flux capacitor, in which case let me know!!) I have nothing tying me to Glasgow (aside from a love of Kelvingrove Park and Saturday nights in The Shed). So the question that remains.......to South Korea or not South Korea?
