I am currently aiming for a lifestyle of uber-cheapness to pay off debt and save money, and I wanted to share ideas with anyone else who has taken on a similar challenge.
So far, here are my ideas:
-Riding a bicycle. Everywhere. For long distances take the local bus or for ultra-long distances take the greyhound bus. The price of a ticket is comparable to the cost of gas of driving your own car, so this saves on insurance, parking, gas (for short distances) as well as, obviously, the entire cost of the car. Coupled with body-weight calisthenics you can do at home for free, this also doubles as a gym membership, if you want to think of it that way.
-Utilities included shared housing. Where I live, a person can get a room of a house or apartment shared with other people with "utilities included" (including wireless internet) for $500. Tough to beat, especially when you're living cheap and don't need a bunch of room to store a bunch of stuff you don't need.
-Voice over IP. Cancel your cellphone contract and landline and use this instead. For 2011, you can make free calls over wifi on your smartphone using the Google Voice SIP. After that, other services are available which allow you to make calling-card rate cheap calls to other countries as well as in the US (such as Skype for smartphones). How do you get calls on the go, you ask? Data-only plans from places like Mrsimcard.com (AT&T preferred) or MySimpleMobile.com (T-Mobile) which provide enough mobile 3G data to your smartphone to make sure you can receive VoIP calls wherever you are, and only about $25/month with no contact. Tough to find that kind of rate with a voice plan.
