Advice from Linda, the TA:

1. From time to time, yell at my roommates to work in teams.
2. Find a rubber spider, paint an hour glass figure on its belly, and engage it in mock-combat with a broom and a cardboard box.
3. Resupply big chalk to every classroom at Harvard.
4. Wake up my roommates at 9am sharp and make them sweep our porch.
5. Monitor the position of our neighbors' cars to make sure they haven't been moved at night.
