When this topic from Long and Short Reviews came up, a story from my past immediately came into my head.
When I was a kid, I went to my primary school summer fair and encountered a stall which claimed to tell your future using numerology. I got a printout with various predictions on it, most of which I can't remember, but one was "With a sharp and technical mind like yours, you would do well in a career like engineering."
Right.
While it's nice to be told you have a sharp and technical mind, even as a child I knew this was absolute nonsense. While I got a double A* in my GCSE Science, that was primarily by sheer determination and my chemistry and biology scores dragging my physics score up. Physics and maths, which are the sorts of subjects you need for engineering, are definitely not my strong subjects, and while I'm good at using a computer I'm certainly not technical. I would be utterly terrible at engineering.
It's probably just as well I can't remember the rest of the predictions, because if that one is anything to go by they weren't worth remembering. I think it did suggest I would get married in my thirties - I was 27, so they got that wrong as well.
So what job wouldn't you be good at?
