I'm happy for you that you're proud of your accomplishments, and I have a lot of friends who have taught overseas and universally it has sounded like a fantastic and rewarding experience (most of them brought back foreign wives even). That said, when I was looking into the possibility of doing this before graduating, a Chinese company even offered to provide a phony degree for me (as a bachelor's degree was a requirement) and hire me right away anyways. And every friend I know who wanted to teach overseas was quickly and easily hired and able to do so. It's not exactly some really elite and difficult to obtain position that only accepts the best of the best.
The thing is, if you wanted to talk about those experiences in a reasonable and humble way I'm sure you could actually have some cool anecdotes that would make you actually sound cultured and experienced and interesting. But explicitly saying "I taught overseas, look how great and successful I am" just makes you look like a dipshit who has never accomplished anything of substance or had a real job because apparently that's the best you've ever been able to do.
P.S. - In keeping with how bitter and angry you are, didn't you also vandalize the wikipedia page of a school you taught at to bitch about your accommodations? But you are now using the same experience as an example of how successful you are?
