10. You Aren't Gaining Relevant Experience
No matter how many wonderful contacts you gain at your internship, if you aren't building a skill set, you won't be employable. Don't get us wrong, you are going to have to do some bitch work, but if your day begins and ends at the filing cabinet, then it's time to reconsider the situation. Janitor, courier, caterer: these are all good jobs that command a decent paycheck. They are not the responsibility of a college junior who is a natural with the Febreze bottle. You're going to be taken advantage of enough in your life in exchange for a paycheck: don't let a company sucker you into a parasitic situation in exchange for transportation costs and a pat on the back.
