Who are they?

The first thing that comes to my mind when I hear the word "Hero" is that the one who saves lives.
Saving lives is an essential thing done by some people who are giving importance to their fellow men. And that is such the greatest thing to be made.
A well-known superhero- Superman is saving people in the movie. He always comes on time to help them and he is not about to what he can benefit to whom he saves but rather he is helping sacrificial.
I have my own heroes which I consider as one of my saviors. Heroes who have brought me in the starting line of my travel. They have been educating me to have knowledge in fighting for ignorance. They are the reason why I am situated to where I am right now.
They are the teachers who have been part of my journey in climbing the ladder of my success. Thanks to you!
