When I Grow Up

You know those people who just knew from the time they were in preschool that they wanted to be a nurse, a doctor, a mechanic, an engineer, etc.? I envy those people.  How do they just know that is what they are suppose to do with their life? A few years ago I taught a sports fitness class to preschoolers and I thought, this is what I am suppose to do, I am meant to be a teacher.  That year I signed up for classes at LCSC for elementary education and I have been taking classes ever since. Lately I have been wondering is teaching really my calling?  I am currently taking Math Methods and I am learning how to teach mathematics to elementary age students.  This concept frightens me because the way I think about math and compute math is exactly the opposite of how they are suppose to be taught. When I mention to people about being unsure of teaching, they say you're just having a bad day, something good will happen to make you realise this is what you're meant to do.  I hope that something will happen soon because I am very discouraged!
