Life is difficult sometimes.

Many people do not understand how hard a teacher's life can be. Your students think you are their enemy, and they do not understand that you are there to help them, parents think that you are not right, that whatever you do is wrong, even you may think that you are not in the right place, you would sometimes prefer to be at home watching the snow falling outside, however you have to go to work. You get there and start the first class where you see that some of your students are interested in what you are talking, though others are trying to study other subject because they have an exam. You get happy because you know that for some students your work is important, and then you realize that your day is worthy. Check the following video about motivation by Heather Tiddens in Youtube.
