I have a few...some of which were already mentioned.
A social media & marketing expert. I did a few internships where I was in charge of a company's social media & marketing. It was great because I felt like I was just playing around with Facebook and at each position, my boss was just so impressed with the results lol
A travel writer. I would love to just travel and get paid to write about it.
A food critic. Same as above, just with food.
And at the top of the list...working for the Chicago White Sox, ideally in a communications role...
