I recently got promoted to a Manager position at Express, and so far I like it. There's a lot of responsibilities that I recently acquired, and sometimes I can't believe I actually put up with such stupid customers that have no shame, but eh. It's challenging, it brings out the competitive side in me, and the perks are fun. It's definitely not something I'm going to do for the rest of my life, but while I'm a student, it's a good part-time job. It's definitely made me a much more social person, and it's helped me mature. I take my job very seriously, and will not have anyone questioning my work ethic, but that's true of school and anything else really.
As for my major, I'm seriously considering switching over to Criminology/Law & Society. I just don't think I have the passion to be a premed major. I may double major and then see which one calls out to me more, but either way, I'll either be going to Law School or Med School.
