Do you watch the news?  Does it profit you anything to know how many little children were murdered today? Can you really alter God's plan for the world?

II Timothy 3:13

But evil men and seducers shall wax worse and worse, deceiving, and being deceived.

Matthew 24:12

And because iniquity shall abound, the love of many shall wax cold.

I have found that it takes your focus off what God desires and occupies valuable mind space.

Isaiah 33: 15

He that walketh righteously, and speaketh uprightly; he that despiseth the gain of oppressions, that shaketh his hands from holding of bribes, that stoppeth his ears from hearing of blood, and shutteth his eyes from seeing evil; 

Philippians 4:8

Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
