If you want to make money, go and train to be a plumber.

If you're a kid and you want to be making money (or at least a comfortable living) in 20 year's time, become a farrier.

Because we are going to be ploughing with horses again soon, the way things are going. And even if we're not, a horse needs shod every couple of months and costs a couple of hundred every time.

I've never seen a hungry-looking farrier or scrap metal dealer.
