oh lord...i usually had 2 or 3 jobs at a time!
i worked in my dorm's office (night shifts), worked as a housecleaner, did yardwork/minor construction, university reasearch lab (my undergrad during school, then another one durning the summer), and a private lab, and taught freshman biology lab. i've also been a volunteer emt/rescue squad member for 3 years (the volunteer emts respond to 911 calls in my county). while i was doing some post-bacc stuff after i graduated, i worked 30-40 hours a week at the clinical research center that i'm now full-time at. i was a busy girl, but i was also paying my own way. so it all worked out.
