I have always believed in the saying "garbage in, garbage out". What we expose ourselves to, through what we watch on television, who we befriend, even what blood relatives we allow to remain in our lives, comes out in other forms through us, in our interactions with others.
If we expose ourselves to goodness, quality people and love, then I believe, what we will exude to others is peace. I hear some people say that goodness, and good people are hard to find. There was a time in my life when I would have said that, yes, but what I find more is that good people are everywhere around me, I just have to put myself in the right places to see it. Quality, not quantity.
