As for me, like I said, I too didn't want a desk job. I was naturally good at math/science and enjoy engaging with people and trying to solve business problems. While I was in my junior year of college I went to my advisor and shared my tied-to-a-desk concern about engineering and also my other passions - she recommended I get a business marketing degree. I did that and did a paid internship my junior/senior year in the field I'm in now. That gave me the confidence back then that I was on the right path for me.
I hope this helps. You're wise to think about the kind of work you want to do and the environment you want to work in.
