I've always thought that I'm jealous of my friends who have achieved greatness in their own ways, but I then realized that if you exert enough effort, chances are you will make it as well.

You must be self-confident, modest, in possession of an indomitable spirit, persevering, and ethical. These are the tenets which I learned from martial arts class.
