During my time in undergrad, I spent a year as a design team captain. Specifically, running a team that builds and flies rockets. I also spent several years trying (and failing) to get another design team off the ground1.
I think this was quite possibly one of the most valuable experiences I could have had as a nerdy, young, somewhat immature soon-to-be-professional with questionable social skills and very little idea of what it’s like to be on the managerial side of things. It’s a big reason why I am the person I am today.
