Have you ever used your phone's GPS? When you ignore what it says and go a different way, what happens? You get lost, it takes longer, and sometimes you don't even get where you wanted to go!
Parents, teachers, grandparents, they're like life's GPS. They've already walked the road before you, made mistakes, learned, and now they're trying to give you the right coordinates. When you accept their advice, you shorten the road. When you ignore it, you might take years to discover what they learned in one. And you know Who has the best GPS of all? Jesus! He doesn't just know every path, He IS the Path!
