Have to be strong-

In this world you  must be strong. One fad becomes old, when another comes along. In the world, it's wise and good to be peaceful; but things are done via strongly, because we are human. We come from ancestors who ran wild in jungles and caves, who used to prey on another for food- who for millions of years had no language all we did was 'grunt' or moan to show our feelings. So it all starts with being strong. So when someone comes and says there needs to world peace, you have to really look long and hard at him or her. Because everything mankind achieves and settles on is strong.
