I took the Cisco networking electives, being the geek I was. I slept through 90% of it, it was such a terrible experience. Ironically, there was a very popular shop class where effectively the entire student population knew who the shop teacher was and I chose to take the networking because I didn't have any interest in shop.

Now I have a garage full of woodworking equipment (and wood), spend my leisure time watching youtube and building things.. sometimes I wonder if I would have ever made it to software professionally had I taken that shop class. Might have ended up making cabinets :D
