My first—and very brief—job out of college was with an after-school mentoring program that trained kids in woodworking. When I was asked during the interview if I could teach woodworking, I responded in the affirmative: “Sure!” How hard can it be? I thought to myself. But I had never worked with wood. So when I attempted my first project and mangled a piece of fine wood with a belt sander, my boss took one look at it and fired me on the spot! Clearly, I had no idea what I was talking about.
