Let me be the first to say that I really don't know very much about cars and how they work. My strategy is to try and find a service provider that I trust and then listen thoughtfully to what they say before okaying the procedures and paying the bill. And yet... there's always a nagging insecurity that somebody is taking advantage of what I don't know.
I can't count the number of times my students have asked me why they need to learn this or that. My answer is always the same: we want you to learn how to learn and learn how to communicate what you know so that you can get what you want from this one short life.
And kids? Take it from me. There's a lot to know.
Life Lesson: I think it's pretty obvious.
