You are in studying in a bilingual school IN Thailand. Imagine yourself studying abroad in a boarding school where NO ONE spoke Thai.

I lived through that. You can, too.

Don't compare yourself with your past. You might've been an 'high-grade' student in a Thai-speaking school, but how did you achieve that? You studied hard, right. It's the same thing, except that now it's a different language.

You might not be able to get to where you were before, but you're going to GAIN more from learning English.

Hey, there's no such thing as a 'free lunch'. You've just got to believe in yourself and work you way to it.

Enjoy!
