Knowledge is certainly powerful but knowing something isn’t always enough. I’m sure you’ve heard that eating more fruit and vegetables is better than that bag of Doritos, right? You know that exercising and eating healthy is good for you, but knowing alone does not create change. Some of you may smoke even though you see that warning on the cigarette pack and you watch those horrific commercials. You know that smoking isn’t good for you and yet, this knowledge is not enough to change your mind.
