The worst moment in my life is when I decided to left the school about thirty years ago, I was studying the bachelor degree in mathematics, it was really difficult because my family was really poor and then I had to work in order to pay my tuition, I almost had not time to sleep, then I get depress. Now I am studying again but management of human resources on line, it is very difficult to but I think this time I will finish no matters that I am older the fifty.
