You know, why do people coming to Thailand just resort to teaching when they hate and get burnt out so quickly? Having a teaching is just a way to get a visa IMHO.
It doesn't matter what your skills are, you can get income from just about anywhere you are. You must only know how to hone your skills and market them.
Lately, I've been making more money from freelancing than I ever earned from teaching and I'm a lot happier. Check out sologig.com elance.com or any other great freelancing site.You can find lots of work up there, heck even Amazon's Mechanical Turk has ways to make money.
If you can write, have computer skills, or you are just plain tenacious, you can earn more money per hour than you can teaching. There's no reason to get burnt out.
