A hero (heroine is usually used for females)*, so it’s a person… who changes the world… in themselves!

We call heroes people who found strength in themselves and decided to change

Anyone can change the world, in (his) own words and actions. But above all, he must change in themselves. Of course now I’m talking about people who are addicted to illegal drugs such as heroin, cocaine or marijuana and alcohol. They themselves must find a lot of strength to stop using drugs and begin to change.
