What are your best money saving strategies?

For example, where do you spend and where do you skimp?
Do you use coupons when you shop?
Do you never go out to eat?

I’m a student with loans over my head, and I’m trying to make 2009 a year of really learning how to budget, manage, and save money. I am EAGERLY awaiting your responses. :)
Essentials only. Dining out – bottled water, beer/wine, cigarettes, gym membership, prepared foods are not necessary for life. Coupons are fine – unless you can buy a different brand cheaper still. Cheaper toilet paper may not be as nice, so you have to decide just what is really important to you. Start from the bottom up on your need for life list. Air, Water, Food, shelter – utilities. Every area has room for skimping.
