Ask HN: Teach me to think like an engineer

A few years ago I often heard this advice: go to law school, because it will teach you how to think. Nowadays I keep hearing, reading or experiencing for myself that law school has been replaced with engineering, with many pundits citing someone's background in engineering as the key factor that helped them solve all manner of non-engineering problems. For example, from the WaPo piece on Edward Snowden currently on the frontpage: "Snowden is an orderly thinker, with an engineer’s approach to problem-solving." How can I learn to be an "orderly thinker"?
