What do I fill my heart with?

I remember getting into arguments with my youth pastor about how music effects you. I was convinced that since I was a country music fan that the messages of the songs were just about life... It wasn't until years later when I went back to some of that music and realized in more depth what they were singing about and somethings about the different artists that I began to start understanding what he was trying to get us to see. That whole phrase, "garbage in, garbage out" really is true. I find that if I am reading, listening, watching things that are not uplifting they are filling my mind. If I watch a scary movie I have have a night mare. It happens every time. How can I justify watching something like that if it's going to mess with my mind. The movie probably didn't even scare me when I was watching but it will scare me during my sleep. And then there's the times when I would hear myself humming a song that I know is promoting things that I don't agree with.

I am particularly interested in staying away from things that are geared at encouraging young women to not focus on the  wonder of their purity. I make it a conscious effort to filter what I allow into my mind and heart. I block apps on facebook that promote an ungodly idea of who I am; I don't read magazines that encourage women to look at themselves as sex objects.

Philippians 4:8 Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.
