Twenty odd years ago I was doing an apprenticeship as a die cast diemaker. That particular night I was working on the lathe, turning out custom core blanks for later precision grinding. The boss came by and got in conversation with my journeyman, asking how I was doing in that area. The journeyman showed him all the job orders I had completed that week, talked about learning to change lathe heads, etc. Boss wanted to know when I'd made my last mistake. It seems he thought the only way to learn was to do something wrong once in a while.
