David and Goliath

I read a story in one of Dr. Phil's books. It has been something that has been on my mind this past week because it is about your perspective. He says that when the townspeople saw Goliath they said, "He's so big, we can't defeat him." When David saw Goliath, he said, "He's so big I can't miss him!" I have applied this to my "Goliaths" this week. I am realizing there is so much power in how we look at something. Is my problem so big I don't believe I can defeat, or is the problem so big there's no way I can miss it?
