Who are your heroes? It is really an enlightening exercise to sit for a minute and ponder this question. Are your heroes, perhaps, people who fought against injustice, spoke out when they could have remained silent, ran into danger to save others, had a vision for the world that transcended the accepted theories?
It tells us something of ourselves to consider our heroes and perhaps points a way to where we might use our voices or actions to better the world.
No matter who our heroes are, though, it is unlikely they acted fearlessly. It is far more likely that they understood the dangers, were afraid, but did it anyway because it was important.
We can, too.
