Our world as it is today, is quite different from what it used to be. In the past, survival was a struggle. Humanity was nomadic in nature, so we did not have homes or safety. Every meal was a fight. Then, we finally learned how to grow food and build permanent homes.
When we no longer had to fight nature, we began to fight each other. There were wars and genocides in our past. There were plagues and famines. However, our ancestors endured through it all. They were courageous.
In the past, courage meant far more than just being brave. Courage meant being able to find a single sliver of hope in unbearable, unrelenting darkness and clinging to it. Courage meant holding your own dreams hostage because sacrifice was the only way for you or your loved ones to live. Courage meant being a good person even when you were powerless and suffering.
