World peace is an extremely simple concept, but it is near impossible to achieve.  In order for any kind of peace to be possible between two people, one must find peace within himself.  We must be able to work without fear of losing what we work for and without fear of others stealing our belongings.  We must be able to rid our hearts and brains of hatred, fear, anger, and greed.  With peace, we will be able to sleep at night without our doors locked, without fear of others.  We must trust others and trust ourselves.  Peace is only attainable after we find peace within ourselves.
