A chef's life is like Groundhog Day. The same stuff over and over. Also lots of quoting Bill Murray. Point being, you can teach someone to peel an onion once, but not how to peel it a thousand times.
Not to be scared of knives
You're going to get cut, sliced, stabbed, slit, and every single other verb that has to do with pain by a sharp thing. If you've got the fear, you're only going to hurt yourself worse. And you're not going to see anyone losing fingers in culinary school to fry your shock sensors.
