Well I have my own concept about teaching, teaching is excellent, teaching is the best way to built a better world, to fight against poverty and illiteracy, but teaching is not just teaching, what I mean is that if you are a professor or if you are going to be a professor you must to be avaliable not only to explain a concept or something, but also you must to be avaliable to help people, to listen to them and try to give them advice. Nice thing that they let you know that someone you talked to is progressing because the advice you gave him/her. There is nothing more pleasant than watching that huge laugh in your students' face, this is the best reward !
Lets Fight against poverty and illiteracy !
Remember, Working hard is important, but there is something that matters even more, believing in yourself !
