We cannot give up hope for the future of humanity because it is our destiny to shape that future for good or ill.

Nothing is predestined. The obstacles of your past can become the gateways that lead to new beginnings.

You can't change where you come from, but you can change where you go from here. Just like a book. If you don't like the ending, you can make up a new one.

Humanity has the stars in its future, and that future is too important to be lost under the burden of juvenile folly and ignorant superstition

Never laugh at the fate of others, you are the next
