do i speak how i write?

Before starting this saga, I mentally framed it (created a mission statement so to speak) thus: I'm moving to someplace I've never heard of where I don't know anybody to do something I've never done before. Sink or swim. The school will buy me a plane ticket home or to wherever I want to go if I complete a year's worth of work, or seven seven weeklong sessions. But, I realized that this was a pretty aggressive and crazy plan and so, making good on a 2008 resolution, I set up a plan b. Actually, teaching English abroad was also a plan b which I'm really proud of myself for putting into effect finally. I will reconsider my year after two sessions, after fourteen weeks, after three months because "you can do anything for three months." Whatever my decision here, I will create a new plan.
Well, I've learned a lot about Yemen, met a lot of people, and as of this week have finished my teaching my first session. This last part was my greatest apprehension and I feel warrants some thoughts since I'm realistic about the future and pretty much I "gotta go to work, gotta go to work, gotta have a job." *Wince. This is my halfway mark.
Teaching is pretty easy. I feel really comfortable with the students and they both seem to like class and are learning. All of my students passed and none of them said it was easy which I consider a good thing. Connecting to my students is probably my strongest suit as a teacher, which makes the material accessible for them. The problem is curriculum and what to do with all the time. The school is designed around a schedule of standardized tests and essentially my job is to get students to pass the tests, to give them what they pay for which is a certificate saying they know English and not the actual knowledge of English. This part annoys me because a lot of the time I have to slow down to adhere to this schedule rather than work at the pace the students are learning. I feel that the students could learn a lot more for what they pay if it weren't for the damn tests. My classroom is micromanaged. So my job is a lot of the uneconomical killing of time which causes me to think about it at home, which I loathe. Anyways, ultimately, the job's okay, I could do this for a year and could teach for the rest of my life but probably not English and probably not abroad.
Work, however, isn't the majority of my life and decidedly so. I've noticed that the things I miss most are nontangible and more than just inconveniences like brown outs and water shortages at night. There's quality of life issues stemming from the lack of freedom of speech, press, gender equality, and recognizable justice. The deep cultural differences are a taxing struggle that becomes more insurmountable with time. The tolerated, even promoted classist, racist, heterosexist cultural norms are an acid that eats away at my psyche. And that scares me, a lot. In the face of this, I don't know how long I can hold out before either I burst and say something imprudent or before my foundation of Americanism (which is admittedly ethnocentric and inherently flawed by the double standard of relative morality) is left in ruins. This begs me to wonder what precisely were my motivations for this endeavor?
