7 year itch?

I've heard of 7 year itch in marriages but 7 year itch in teaching?

I'm experiencing that right now where after 7 years, I kinda dunno what I want out of my career. I've tried the leadership track where I've covered HOD duties for the last 2 years. Frankly, I gotta admit I like the challenge of the work... appeals to the control freak in me. But it's very tiring and sometimes, I'm not too sure if it's all worth it. My health has also suffered as a result of the stress and I've been advised by my doctors (note the plural use!) to watch it and take it easy. They have been nagging at me for the last 2 years!

Lately, seeing my friend and mentor end up in hospital due to a recurring tumour has really put a wake-up call to the advice I've previously taken for granted. I'm really thinking about this very carefully as I really dun hope to have the stress act up strangely in my body, causing cancers or heart diseases.

Maybe it's time to really think about my Plan B in teaching aka teaching English overseas. I've dreamt of it for 7 years and maybe it's time to consider it as a real option?

I've been searching and it seems like Korea comes highly recommended. Maybe it great for the Korean Drama freak in me! Haha....

Must mull and stew over this carefully with much prayers! Plus, I have to clear my exams this time round so I can graduate first... otherwise, it's still poofs of dreams...
