Troubleshooting, as important as it is to engineering and computer science, is a general skill that should be taught to kids starting in pre-school.

I'd argue that you can generalize all non-creative disciplines (science, business, plumbing, etc) down to a specific area of troubleshooting. And for the creative and athletic disciplines, troubleshooting will be needed to get the best output from your tools, be they chisels, oboes, your voice, your muscles, paints, or anything.
