I firmly believe that if you put good things into your mind and soul it will result in good actions and a successful life. It has been said, garbage in garbage out. That is true but let's focus on the good and forget about the garbage.
I try to read blogs everyday that will give me direction and hope. Blogs from authors like Dan Miller, Seth Godin, and Scott Wimberly. I read my Bible and devotional (Great Is Thy Faithfulness by Larry Burkett and Our Daily Bread) daily to remind me of God's faithful and constant love. I listen to upbeat music that contains truth and meets me on a deeper level, washing my soul. It is important to me to have the right things coming into my ears and eyes. In a sense, I am making my life an experiment. As I age, I am applying a thicker filter on what I allow into my life as there is less time and so much good material. So I stay away from books, movies, and people who use bad language. I say "no" to the horror movies and violent films. Fiction is almost always disappointing, so I have set that aside for the most part. Instead, I watch movies with a redeeming story line. I read non-fiction and biographies that give me hope because someone else has overcome obstacles and made it.
I would encourage you to be careful on what you allow into your life. The music, videos and books you consume will affect your beliefs, your actions, and ultimately your legacy.
