For 3 to 4 days, wear the same outfit every day. Eat a lot of instant oatmeal, ramen and/or rice and beans. Drink only water, cheap instant coffee or tea. Reduce the amount you spend on groceries and personal care in half. Forego any form of entertainment or leisure that costs money. Walk or take public transit everywhere. Turn off your TV. Take cold showers. Sleep in a sleeping bag. Only read books from your local library.
