My advise is you have to ask yourself if you are prepared to make sacrifices for something that you believed in. If you go in with the correct mindset and mentally ready to adjust your lifestyle for a cause that you are passionate about, you will be fine. Otherwise life may be miserable and add one more headcount to those who break bond or resign immediately after serving the bond. There are some in every batch of fresh NIE graduates. I have seen 2 in 3 resigned from one batch once. Those who resign will lament that they "lost" 4 good years of working experience because teachers' experience are in general not considered for "additional" starting pay in the private sector.
