1) Ignore it - Matthew 24: 6 " ... but see to it that you are not alarmed." The end of the world is going to happen. Don't fret over what you see taking place.
2) Believe in The End - This works two ways. First of all believe that this world will come to a cataclysmic end (Revelation). Secondly believe the Jesus has a alternative ending for us, His followers. 1 Thessalonians 4:16-17
3) Understand why you are here - Most people live to meet their own needs. Jesus said that He would do that, we were here to fulfill His will. Acts 1:8
4) Reach this world with the Good News about Jesus - Before it is to late! John 9:4
5) Enjoy life NOW!! - Things such as hope, joy, love and so much more are for us now! I Cor. 13. Even in the midst of life's unfair deeds, Jesus is still Lord and we are still the children of God.
