dude.. wait tables.
I did three main jobs before med school: taught english overseas (1-year), played/taught guitar, and waited..
the stuff i learned at the restaurant helped me waaaay more in med school than any of my undergrad classes or volunteering stuff. If you can read people, know how to reach them, know what they want, recognize body language, *multi-task*, make people comfortable instantly, deal with customers bull**** and messy situations, you will be a rockstar waiter and third-year med stud. seriously waiting is STRESSFUL (try rocking a 6 table section on friday night..) and it prepares you for a lot of the crazy interpersonal **** that happens in the hospital. plus there are always girls in restaurants and it's a fun crowd to work with..
