Just a thought, if we more or less 'avoid' those things, such as all those wars you stated, avoid being reminded of them, would we then automatically have less negative thougts and more positive thougts?
Nowadays we are constantly reminded of all the negative things by the media. The media more or less loves negative and sensational news, since that gets the attention. Sure there are positive stories in the news, but there will always be more negative stories. If they state that some war has ended, you are still reminded of that particular war and thus negativity in general.
I think I understand why Steve gave up news and television.
In fact, I'm trying to avoid the news too nowadays, because if you think about it, it doesn't really have _any_ direct value to you, it will get you in to negative thinking more often than not, which naturally would work on the law of attraction, which creates more bad things, which you get pointed to via the media, which makes you think about those bad things, which works on the law of attraction, etc etc..
