If You had power to change the world, what would you change??

there's a saying, unless we learn from our mistakes and a total renewal immediately takes place is a sign of inner strength that can be attained with God's help. perhaps, the best thing i'm going to do (if i have a super power to change the world in a limited time) is to put all this sentiments to the people around the world. for the fulfillment of this sentiments we feel can be passed on to generations. then the world will be change slowly into ONE where there's abundance instead of poverty, love instead of hatred, and peace instead of war.
