From Tiger Tribe
I recently wrote about how some people may think that TEFL is a dead-end job and since the grass is always greener they might try to get another job. After sending out endless CVs and going to interviews and doing demo lessons you might finally realize that it's not worth it.The unknown is scary. Even if you have issues with your job, or your boss, or your co-workers, you know how everything works. That's why some people stay so long at one job or in one country: it's the easy way out. There's nothing wrong with that. People like to stay within their comfort zone.
Other people would disagree and say that if you want to move on, you have to move on. In order to get that fantastic job you have to move outside of your comfort zone.
