<human>: I'm going to be a sophomore in college, majoring in mechanical engineering. I know I want to stick with mechanical engineering, because I'm very interested in it, but there are so many fields you can go into with that degree. I live in the US. I have very broad interests, and originally was attracted to Reddit because of how much interesting stuff I could learn about here. Over the years, I have considered all sorts of futures, from agriculture/farming to architecture to social work to engineering to music to teaching to politics to a "living off the land" lifestyle. I'm very passionate about service work, and want my job to help people in some way. My real goal in life is to make the world a better place.

Can you condense the text into three sentences or less?
<bot>: I have very broad interests, but I'm having a tough time drawing the connection between an engineering degree and changing the world.
