It's hard to say exactly without more context. It could be the name of a book or a performance.

One success story could be a cadet who overcame great physical challenges during training. He started out not being very fit but through sheer determination and the strict training regime at IMA, he managed to build up his strength and endurance. He then went on to lead his unit in a difficult military exercise, showing excellent leadership skills that he had developed during his cadet days.
Hard work is a crucial element. Cadets have to put in long hours of training and study. For example, they might have to wake up early for physical training and then spend the rest of the day in classes and practical military sessions.

I'm not entirely sure as I haven't read it in detail. But generally, it might be about a character who decides to stop being a hero. This could involve things like the character being tired of the hero life, facing moral dilemmas in heroics, or having some personal issues that make them want to quit.
