I'm pretty sure a lot of engineers have "designed bridges" in their free time as a teenager before they realized they wanted to be an engineer. Hell I did a huge amount of hardware tinkering for both legal and illegal reasons when I was in highschool. Build various phreaking boxes, tesla coils, radio frequency overiding devices, and all sorts of other crap. I could have either became an electrical engineer or a programmer, but I chose the latter cause it's really what I love to do.
