I found that sausage factories training centres mostly involved kiddie work, so moving to public primary and middle school wasn't much of a stretch for me. The hours? After my first semester, I was able to pick up extra hours and do them standing on my head. 30, 35 class hours a week? Bring it on, I said. And I did. What I found after a time was that lack of defined objectives turned it into a grind. Or rather, playing the game (with Chinese characteristics) of pretending to accomplish something when they're really unwilling to let you accomplish anything wore me down. From the teachers I know back home, they all make similar noises (without the Ch characteristics). It ain't the years, its the mileage. It ain't the hours, its the crap you put up with that stands between yourself and the completion of a job worth doing and worth doing well.
