Nix going out to eat, even if its fast food. Not only will you save a ton of money but you'll eat healthier if you prepare your food yourself. Also, think ahead when you get your paycheck and set aside money for every bill and gas that you'll need until you get paid again. What's left is for food and entertainment.
I'm in my twenties and have friends who like to have a drink at the bar...I really like beer, and if someone else is driving will drink about 4 in a night. Instead I offer to DD, so I have one MAYBE two (depending on how long we are out) light beer(s). It saves me calories, I still get to have fun with my friends AND everyone gets home safely.
We love going to opening receptions for art exhibitions. There is always food--usually healthy stuff like veggies, fruit, and cheeses and sometimes wine (stay away from the soda and junk). Dinner, entertainment, social interaction, and learning and seeing new stuff. It is a win on all levels!

Instead of paying large monthly sums for cable or satellite television, we use a Netflix account to watch movies and our favorite TV episodes. Online "watch instantly" options are great and provide endless entertainment options.
